We lead a walk for Sequoia Audubon Society from Point San Bruno to Colma Creek channel and back, with 9 total participants. About halfway along, it started to rain, although not heavily. It was, however, cold. You've got to hand it to birders: we're standing on Scavenger Marsh Bridge, in the wind tunnel, trying to ID a gull on the transfer station roof. The Ruddy Turnstones were great, and new for us at this site.
