Baltimore and DC have free buses called "circulators". There was a story that the buses are losing money but would lose more money if they charged because they're getting grants for being free and have ads which would be worth less with lower ridership.

Interesting, since they used to charge!

I suspect they also make some of the money "back" from people taking the bus to/from a Metro (subway) stop, where you now have to buy a ticket since you no longer have a transfer.
