I find that most bike racks tend to be very poorly designed, and dont allow for very safe lock-ups if you use them the way they were intended. Most of the time Id rather find a parking meter than use em. But here are some really neat ones here in philly. I saw one the other day that was a sculpture of a giant chainring, and a piece of chain around it, and attached to the ground, I meant to take a picture of it on the way back but forgot. Later on down the same street I saw this one that looks like a devil or bull riding a bike( sorry for the REALLY ****ty pic.. but I broke my camera, and my phones camera does weird **** sometimes.. .but notice the horns on the front of the "Devil")... anyone else have pics of interesting racks?
