If you’re a 1) transit nerd, 2) bike geek, and 3) frugal, you won’t find a better souvenir of the Bay Area than a free Caltrain bike destination tag. These plastic freebies are used for grouping bikes by destination in the bike car and available from the conductors onboard the train.
I only hope nobody tries to steal my tag back here in NYC.
