From SFBC ^[1]:

San Francisco is the West’s West, but when was the last time you pedaled all the way out to the Pacific Plate? This ride will take a loping, loving look at the City’s western edge, stopping to explore curiosities and celebrities along the way, ruins and relics and remarkable riches.

2 hour ride; have a big lunch beforehand, we’ll stop somewhere for a snack. SF Bicycle Coalition recreational rides are free for members (a $5 donation from non-members is appreciated); rain cancels rides. Contact Andy ^[2] more info.
