How To Train Hop from Jeff Seal on Vimeo.
Last year, after he returned from a four day rail jaunt, we asked Seal how dangerous this sort of thing really is (it's obviously illegal). He told us, "I guess it's dangerous, but I don't know. It's one of those things where if you know what you're doing, it's not that dangerous. I wasn't too worried. I guess if I got my legs chopped off I would be kind of screwed, but I don't know. I didn't think that would happen." And look—one year later, and he's still got both stems!
