Celebrating the colorful history of Tomales, this year’s annual Tomales Founders Day is themed “Old California” and commemorates the generations of residents who’ve called the town home since Europeans reached the bay over 150 years ago. Highlighting the volunteer-run event is a parade that travels along scenic Highway 1 and concludes at a big-top tent. Live music from country rockers Transistor Rodeo and Randy & the Special Agents keeps the fun moving throughout the day. Barbecued oysters and other delicious food feed the masses while kids’ activities, craft booths, farm demonstrations and more embrace all things Tomales on Sunday, Sept. 4, Shoreline Highway, downtown Tomales. Noon. Free admission. 707.879.8202.
