From 2001:
I commute to work each day from San Francisco to Oakland on BART.
The following are some sketches I've (stealthfully) made of my fellow passengers as they read or snooze their way through the tunnel under San Francisco Bay.
It isn't a very long trip, so I have to be fast and sneaky.
My apologies if you unexpectedly find yourself one of the subjects of my BART doodles...
