Former Olympia Farms Property on the Rancho Potrero Open Space

The Rancho Potrero Open Space area is located in Newbury Park off of Lynn Road, just east of the intersection with Rancho Dos Vientos. The area includes an equestrian center where Rancho Potrero Community Equestrian Center is located and is adjacent to the Rancho Sierra Vista/Satwiwa area in the Santa Monica Mountains National Recreation Area.

On the west end of the space is a a property that used to be called Olympia Farms, which was owned by Greek immigrant, textile businessman and Arabian horse breeder George Patarias Huck. (Huck was tragically shot and killed in front of his home in Mt. Olympus in August 1984 at age 46.)

Huck's 638 acre property was sold to the Mountains Recreation and Conservancy, City of Thousand Oaks, Conejo Recreation and Park District and National Park Service for $4.2 million in 1993. 312 acres were carved out as an addition to Rancho Sierra Vista. The remainder is part of Rancho Potrero, which is maintained by the Conejo Open Space Conservation Agency (COSCA).

In the 2021-2022 time frame, the Olympia Farms space was redeveloped and improved to include, pedestrian paths, a horse corral, drinking fountain for people and animals, picnic benches and a small amphitheater area. More info and footage at THIS LINK.

NOTE: THE SITE WAS REDEVELOPED IN 2021-2022 AND THE OLD RANCH BUILDING LUMBER DISCUSSED BELOW I BELIEVE IS IN STORAGE WITH THE CRPD.

These old ranch buildings are actually a Ventura County historical point of interest that was designated as such in May 1986. According to the City of Thousand Oaks, there were two large barns built in 1930 on the Dos Vientos Ranch. Joseph Lewis, business partner of City of Camarillo namesake Adolfo Camarillo, farmed 8,000 acres of land in this area. The barns were dismantled to make room for home development in Dos Vientos and the lumber currently resides here. The Conejo Recreation & Park District is working with the Conejo Valley Historical Society in finding other appropriate uses for these materials, such as displays at the Stagecoach Inn Museum in Newbury Park.

Over 25 Things to Do in Agoura Hills

The City of Agoura Hills incorporated in 1982 and is part of Los Angeles County. But we consider Agoura to be part of our family, consisting of Thousand Oaks, Newbury Park, Westlake Village, Oak Park and other communities that form the Conejo Valley.

Agoura Hills has an area of 7.86 square miles, with a population of approximately 20,000. It became the 83rd city in Los Angeles County when residents voted to incorporate, just one year after neighboring city Westlake Village incorporated.

Here is a compilation of things to do in the City of Agoura Hills.

Trails and Hiking

• Malibu Creek State Park is an 8,000 acre wonderland of trails, hiking, camping and other outdoor activities. The Hike to the Rock Pool at Malibu Creek State Park is extremely popular. Equally if not more popular is the hike to the M*A*S*H television show set.

• Cheeseboro/Palo Comado Canyons include 4,000 acres of terrain with dozens of miles of trails to explore in the northernmost section of the Santa Monica Mountain range. Popular with cyclists, runners and hikers.

Sadly, the Woolsey Fire in November 2018 destroyed the historic structures at the park. However, four new structures will be constructed by the fall of 2024.

• The 64 acre Peter Strauss Ranch in Agoura Hills is also managed by the National Park Service and features hiking and an outdoor amphitheater area.

A "must do" in the Agoura Hills area is the hike to the old M*A*S*H TV series set in Malibu Creek State Park.

Aviation Museum of Santa Paula is Open to the Public the First Sunday of Each Month

The Santa Paula Airport was dedicated in August 1930. Today it is a non-towered facility with nearly 300 aircraft, handling approximately 97,000 arrivals/departures a year. Much of the original 1930’s-era facilities still exist and are used today, giving the airport a very authentic representation of the Golden Age of Aviation.

Located at the Santa Paula Airport, the Aviation Museum of Santa Paula is open the first Sunday of each month, with an array of hangars open to the public from 10 a.m. to 2 p.m.

Upcoming dates: September 7, October 5, November 2, December 7

Each of the privately owned hangars houses a variety of vintage aircraft and collections of various types, as well as other memorabilia, such as antique radios, model aircraft and race cars. Some hangars celebrate highlights of fascinating aviation careers, while others contain antique aircraft undergoing the process of restoration. Hangar owners or docents are available to answer questions. 

You've got to take the time to stop by. It is fun, low key and quite interesting. The hangars are directly adjacent to the airfield, so you are guaranteed to see aircraft taking off and landing up close.

Obviously an aviation aficionado in this hangar!

The participating hangars are fairly well spread out at the 51 acre airport but if you're not up for walking, there's a complimentary tram that will take you around. These are some very nice people who have obvious passion for what they do and enjoy sharing it with the general public. I struck up conversations with several hangar owners and they were full of great stories and information.

There is no charge for visiting the Aviation Museum, though donations are welcomed. Visit www.aviationmuseumofsantapaula.org or call 805.525.1109 for more information.

The Museum is not open on rainy days.

Directions: Arriving by car from the east, exit the Santa Paula Freeway (SR 126) at 10th street, turn right off the ramp, and then a quick left onto Harvard Boulevard. Turn left at the next signal at Eighth Street, under the freeway, left onto Santa Maria Street and park in the lot. Arriving from the west, exit the freeway at Palm Avenue, turn right and then a quick left onto Santa Maria Street, about a half mile to the end at the parking lot.

Lots to see, both inside and outside of the hangars.

The History of Lake Sherwood

Lake Sherwood as seen from the Sandstone Peak trail in the Santa Monica Mountains.

Lake Sherwood is an unincorporated community of about 1,500 residents in Ventura County overlooking the Lake Sherwood reservoir. It is south of Thousand Oaks and west of Westlake Village, off of Potrero Road,  accessible via Westlake Boulevard on the east and Wendy Drive and Reino Road in Newbury Park on the west.

For centuries, the Conejo Valley was inhabited by the Chumash. The Spanish came into the picture in the late 18th century and, when passing through what is now Hidden Valley, named the area the Potrero Valley.

The Potrero Valley was part of the original 48,761 acres constituting Rancho El Conejo. After California became the 31st state in 1850, a land commission was appointed to determine who owned land grants in the area.

Rancho El Conejo was sold in 1872 to John Edwards and Howard Mills. Mills received 22,240 acres that included the Potrero Valley in 1874. Mills sold the southeastern 8,476 acres to Joseph and Isabell McLaren Howard in 1875.

In 1888, the Howards sold the land to the Banning Company of Long Beach. In 1896, W. H. Matthiessen bought the Potrero Ranch from Banning. Then in 1904, Matthiessen built a 45 foot dam (originally called Alturas Dam) that created Potrero Lake (also referred to as Lake Matthiessen). Total capacity of the 156 acre lake, which today is called Lake Sherwood, is 877 million gallons of water.

In the early 1920s, the area around the lake was transformed into Sherwood Forest for the filming of Robin Hood, featuring Douglas Fairbanks. And of course that's where the name Lake Sherwood originated.

Meanwhile, W. H.'s son F. W. "Christy" Matthiessen married Elsie Mack in 1917. The couple made plans to develop the surrounding area as the Las Turas Lake Club in the 1920s. Except...they divorced in 1925, with Elsie receiving the portion of the ranch with the lake.

Elsie remarried. Her new husband's name was James Canterbury and briefly the lake became Lake Canterbury. After the stock market crash of 1929, the Canterburys sold the property to William Randolph Hearst. Hearst allowed the property to be used for filming of many films, including the 1938 The Adventures of Robin Hood.

In 1963, Dayton Realty purchased the lake and surrounding property. Dayton wanted to rezone the land to develop nearly 1,400 homes and commercial properties. This plan was fought off by local residents and rejected by the Ventura County Board of Supervisors.

From late 1983 to summer 1984, Dayton drained the lake, indicating that it needed to test the dam...which never happened...then never refilled the lake, leaving thousands of fish stranded and left to die in the mud. (Photo of draining of lake in January 1984)

Lake Sherwood was made available to the public after the depression of the 1930s until the lake was emptied in 1984.

In 1985, billionaire businessman David Murdock bought the dry Lake Sherwood lake bed and surrounding property.  His Ventura Farms and Lake Sherwood Ranch are located on the old F. W. Matthiessen property in Hidden Valley.

In 1986, heavy rains filled Lake Sherwood back up, though it would take many years for the lake to regain the wildlife it lost after it was emptied.

Murdock developed the community with over 650 homes in three gated neighborhoods along with the Sherwood Country Club and Sherwood Lake Club. The lake is now privately owned and is not open to the general public. Murdock passed away at the age of 102 on June 9, 2025.

Incident with Janye Mansfield's Six Year Old Son at Jungleland Thousand Oaks in November 1966

In November 1966, actress Jayne Mansfield was at Jungleland in Thousand Oaks with her three children, Zoltan (6), Miklos (7) and Mariska (2). Zoltan was attacked by a "tame" lion during the visit. The lion had the boy's head in its jaws before zoo employees were able to pry the lion off. Zoltan eventually recovered, after spending a month at Conejo Valley Hospital.

Manfield died in a car crash in June 1967. The two other adults in the car also died on impact. Her children were asleep in the back seat and they all survived. They were subsequently raised by their father*, Hungarian bodybuilder/actor and 1955 Mr. Universe Mickey Hargitay. And we all know his daughter, award-winning actress Mariska Hargitay.

Mansfield sued Jungleland for $1.6 million, which is about $14 million in today's dollars. Jungleland closed its doors and filed for bankruptcy in October 1969. Zoltan received an out of court settlement of $10,000 from Jungleland in bankruptcy. (Note that while the Mansfield incident was not exactly good publicity for Jungleland, the park had already faced financial challenges with the popularity of newer theme parks, Disneyland and Knotts Berry Farm.)

Looking to learn more about Jungleland? Stop by the Stagecoach Inn Museum in Newbury Park, which has a number of artifacts on display.

* In 2025, Mariska announced that her biological father is actually singer Nelson Sardelli, not Mickey Hargitay.

The Twin Ponds Conservation Area in the Conejo Open Space is Protected Land

The Twin Ponds Conservation Area in Dos Vientos is part of the open space lands of the Conejo Open Space Conservation Agency and is protected by a conservation easement to the California Department of Fish and Game.

May 2016

The ponds were originally constructed in the 1920s as part of the irrigation system for agricultural and cattle ranching operations at Dos Vientos Ranch. Today they serve as important habitat for Two Striped Garter Snakes and larger animals such as deer, bobcat, coyote and mountain lions that depend on a reliable source of water. Migrating waterfowl are occasionally abundant, especially in winter.

COSCA and Fish & Game ask that we enjoy this scenic area but protect the ponds for the future and ask that we do not enter the water or allow dogs/horses to enter the water, disturb or remove any animal or plant or place any plants or animals, including fish, into the ponds.

To explore the ponds, take the Vista Del Mar Trail from one of several access points in the Dos Vientos area, including the corner of Via Ricardo and Via Rincon and the corner of Rancho Dos Vientos and Via El Cerro. This is a fun little hike to take the kids on and the ponds are only about a mile from the Via Ricardo/Via Rincon trailhead.

Twin Ponds? What ponds? The ponds are completely dried up as of August/September 2016.

State Route 23 Between the 101 and 118 is Dedicated to Japanese American World War II Soldiers

Moorpark Freeway section of SR 23 taken from Marview Trail in Thousand Oaks.

State Route 23 stretches from Malibu to Fillmore in three sections. The south section is the winding, hilly Decker Canyon Road that connects Pacific Coast Highway to Westlake Village and Hidden Valley. This section is approximately 10 miles from PCH to the Potrero Road intersection, but generally takes 20 to 25 minutes to drive.

SR 23 continues as Westlake Boulevard to the Ventura Freeway (U.S. Route 101), where it runs concurrent with the 101 north a couple miles until you reach the Moorpark Freeway overpass. This is another 4 to 4 1/2 miles.

The most visible section of SR 23 in Thousand Oaks is the Moorpark Freeway, which stretches from the 101 to the Los Angeles Avenue exit in Moorpark; about 8 miles. This middle section of the 23 was named the Military Intelligence Service Memorial Highway in 1994 by the California State Assembly. The renaming was made in honor of Nisei, or Japanese American, Soldiers of World War II who served in units of the U.S. Armed Forces comprising the 100/442/MIS triad (Military Intelligence Service, 100th Infantry Battalion and 442nd Regimental Combat Team). **

Military Intelligence Service Memorial Highway sign

The northern section of SR 23 begins at Los Angeles Avenue (SR 118) in Moorpark and goes north as Grimes Canyon Road, ending at SR 126 in Fillmore. This is about a 12 mile stretch includes some eye opening, hilly twists and turns in the Grimes Canyon Road area.

The total length of SR 23 is about 32 miles.

** Some additional clarification from the 1994 legislation: Segments of State Highway Routes 23 and 99 are officially designated as follows: (a) State Highway Route 23, from Highway 101 to Highway 118, as the Military Intelligence Service Memorial Highway. (b) State Highway Route 99, between the Cities of Fresno and Madera, as the 100th Infantry Battalion Memorial Highway. (c) State Highway Route 99, between the Cities of Salida and Manteca, as the 442nd Regimental Combat Team Memorial Highway. Each of the signs to also include "A unit of the 100/422/MIS triad.
