philadelphia has a lot of streetcars. i lost half a tooth because of those damn tracks (drinking had nothing to do with it). biking around philly i just learned to avoid some streets and be extremely careful on others. like whenever the rails turn off the street you are biking on.. thats scary and happens a lot in philly. the bike lanes don’t help, and actually make me feel more frightened since the streets are really narrow and the bike lanes are in the door zone. that said, screw streetcars horse and buggies are the way to go.
