Woah! Not sure how many of you skate, or can appreciate what he's doing here, but it scarcely seems possible. Seriously impressive skills. - Iain Baker

Bob's crazy. He's got a huge backyard park down in California, with a loop because he wanted to try and see if he could ride all the way through it, and then at one point they gapped the upper portion, to make it even more interesting. - OCoG of FF, Jimminy

Yeah - his bowl is the only one i've seen which has vert ramp sizing, but in a bowl. He can transfer all of his moves from a flat wall, to a bowl. I'm pretty sure other skaters must turn up, take one look at it, and crap themselves. Those concrete walls are pretty scary. - Iain Baker
