From the EAST BAY:

Take the BAY BRIDGE (I-80 WEST) towards SAN FRANCISCO.
Once you're in SF stay to the left, you''ll soon be on US-101 SOUTH/SAN JOSE.
Take the first exit (Cesar Chavez, what used to be Army Street) after the split.
This exit splits into four forks, keep to the *extreme* RIGHT: POTRERO AVE.
Merge onto POTRERO AVE.
Make your first RIGHT at the light, onto 25TH ST.
Make your second RIGHT onto SAN BRUNO AVE.
SAN BRUNO will dead-end in two blocks, park at the end of the street. You'll see two metal gates on your right that lead into an industrial shanty town. If the first gate on your right is locked (after 8:00pm) ring the buzzer next to a phone nailed to the mailbox row. Someone will come up and get you. If the gate is open, walk down until it dead-ends and take a right. Tiny is the first door on your right.
There's a buzzer on that door, too.
