Work hard, then play hard as you enjoy the city’s legendary October weather at the annual FOGG Fest (that’s Friends of the Golden Gate, obviously). Spend the morning engaged in some fun volunteer work with Golden Gate National Parks Conservancy, then kick back and reward yourself with yoga, brews, food, DIY craft stations and tunes courtesy DJ Marky Enriquez, a.k.a. Proof. Give your usual Saturday hang special meaning by helping to care for the city’s well-used parks.
