The 1400 mile stretch of road called the Roosevelt Highway (U.S. 101) in the 1920s was re-named Pacific Coast Highway in 1941.
This postcard, from back in the days when it cost only a penny to mail a postcard (the 1930s) indicates "the varying scenery, such as oil being drilled out of the ocean, makes motoring an interesting pastime in California." It shows an image of the Roosevelt Highway between Ventura and Santa Barbara.
Bob then indicates to his dear friend Jane, "Just dropping a line to say all is well in Calif. There's lots of strange things to see in this state. You should be taking your Sunday rides out here."
Now what does Bob mean by that? Well, never mind. Speaking of Ventura and Santa Barbara beaches, visit THIS LINK for public beaches spanning from the Ventura Harbor through Carpinteria and THIS LINK for Santa Barbara area beaches.
