There's a thing called a bus. Who the hell wants to bike across the Bay Bridge?

There are actually bike tour rental things expressly for biking across the bridge, its their advertising.

That's the Golden Gate Bridge, which is shorter and has ped/bike lanes (separate from traffic, IIRC).

The Bay Bridge's western span has no such thing.
