The official summer kickoff is here, even though San Francisco summers are more hat-and-scarf than shorts-and-sandals. Either way, put on some weather-appropriate clothing and stake out some summer fun, from eating oysters in Marin to drinking wine in Napa and Sonoma to driving down the coast to Monterey.
Staying in town? Treat it like a staycation and explore the city. Load up on fried chicken, take the kids out for hot dogs, or just drink beer on a patio somewhere. Or just use the long weekend as an opportunity to check more hotspots or SF essentials off your to-do list.
