It’s the last Presidio Picnic of the season and if you don’t have friends with a boat or a Bay-adjacent rooftop patio, the Presidio’s Main Parade Ground is the next best place to set up and catch all of the Fleet Week action. Spread out your best blanket and warm up your lawn games arm for a day full of al fresco fun and specials from your favorite food trucks, including the Grilled Cheez Guy and Nopalito.
