Every year that I can recall, a vast majority of the homes on Gemini Street and Waverly Avenue south of Dunnigan Street in Camarillo are lit up and decorated with cartoon characters, trains, Santas, snowmen, and plenty of lights and other decorations. Quite a site. Either drive the route or park and walk it. Plenty to see and your kids will love it. From the direction of the 101, take Arneill north past Ponderosa to Dunnigan. Turn right on Dunnigan and Gemini is the 4th street on your right.
