As far as what can go inside that bag? Bring a blanket, empty water bottle, binoculars, and sunscreen. But leave your booze, skateboard, professional camera equipment, tents, spray paint, and dog (sorry, Rocky) at home.
And though it will pain many a Silicon Valley resident, both drones AND selfie sticks are strictly prohibited. (Life can be so cruel.)
Listen up, out-of-towners
If you live in SF, you know this already, but this town gets cold in August. Like, really, really cold. And when the fog rolls in, it gets even colder. It might be sunny and warm when you leave the house at 11am, but it definitely won’t be by late afternoon, so leave your “festival outfit” in the closet and bust out those strategic layers instead.
And at the risk of sounding like your mom: Wear sensible shoes. Or, hey, go ahead and wear your Reefs, just know you’ll resent the sound of every flip and flop when you’re making the long trek out of the park at 10pm.
