This Video Of Skating On the New York Subway is Epic!
Damn this is cool. If you've ever ridden the New York subway (or any crowded underground for that matter) you'll know this sort of thing takes a fair bit of work to film.
It's taken from the Tengu: God of Mischief movie, which you can buy online now.
If nothing else, skip to the end trick of this section, a gap over the subway tracks. It's EPIC!
