this winter, i got to go to keystone for a day. this one character was going off. i dont know who he was, but he was killing the rails, and he also did a switch 5 tip grab i believe. there was those to flat rails, each like 20 feet long or so, right behind each other with like a 3 foot gap in between them. anyways, this guy blindside switch ups over the gap, and then 270s out, then later i saw him switch on, switch up over the kink, to 270 out. it was intense.
