Via the Curbed SF TwitterWire (join us!): Torch heading to the Marina, presumably in search of polo shirt and/or oversized sunglasses. Speculation abounds while the torch is transported via duckboat. INSTA-UPDATE heading into Presidio. May NOT end up in Justin Herman Plaza. Closing ceremonies canceled? INSTA-UPDATE DEUX: TORCH RELAY OVER? Presidio park to hold closing ceremonies?!?!! MADNESS!!!
