The launch party for a large-scale "Paper Airplane" sculpture is happening at Marina Green. Check SFFuncheap for the confirmed date and start time before you head out — details are still circulating. Marina Green is on the northern waterfront at the foot of Buchanan Street; the closest BART is Montgomery or Embarcadero, then a bus or rideshare north. Street parking along Marina Boulevard exists but fills fast on weekends — Safeway on Marina has a lot that tends to have room.

The draw here is the sculpture itself: a large-format paper airplane rendered as a public art installation, which is either a nostalgia object blown up to absurd scale or something genuinely strange to encounter on a waterfront lawn, depending on your tolerance for whimsy rendered in three dimensions. The Green has the bay and the bridge as backdrop, which means even a middling outdoor event looks good. No word yet on food vendors or ticketing — treat it as a free outdoor stop until confirmed otherwise.

If you've got two hours, walk the Green from the yacht harbor east toward the Palace of Fine Arts, double back past the sculpture, and grab something from one of the food trucks that park along Marina Boulevard on weekends.
