I think I was Alex, now you mention it..... My brain is fried lately....
Also, elsewhere in that video is some footage from Gravesend indoor park (r.i.p.) Scott can be seen riding a couple of free standing volcanos. From memory they were at least 5' high, and I'd say probably higher.
Anyhoo, he 360d one of those one time and went so high he hit his head on the roof beam above and knocked himself out. He hit the ground unconcious....... not good. Didn't do any lasting damage though
