It's pretty much Urban Legend central. Very cool. There is a pretty nasty one in there with a guy that was running away from the cops, jumped off a freeway (i think), and landed on a wrought iron spiked fence.
The catch? (sorry about the pun)
His head got stuck, but his body hit the ground, so he was decapitated. there are some pretty gruesome pics..
