The two biggies take place Friday nights through October at Fort Mason Center in SF and Saturday through September nights at The Barn, a new event center in West Sacramento. Both draw hundreds of folks, many with children and dogs in tow. Also catered by Off the Grid: Picnics at the Presidio, held Sundays through October from 11 a.m. to 4 p.m. on the 7-acre Main Parade Ground with food from celebrated local chefs delivered by mobile kitchens—and, for kids and parents, lawn games, yoga and nature-based arts and crafts.
In the Sacramento area, look for other Off the Grid events at the Folsom Outlets on Saturdays and Sundays.
