I ran across a guy in the Snowies a few years back that had a strap-type thing rivited to his tunnel and pulled it over his legs to keep them held in/on the sled. He said he could throw his upper body around enough to get the sled up on a ski to sidehill in the powder. Right before we saw them at the widowmaker his buddies said he put up a highmark and rolled the sled. THey saw the him go under the sled, the track, him pop back up when the sled came over, him go under, track, ect...about 3 times. They couldn't even tell the story they were laughing so hard, but the guy had a great sense of humor and thought it was pretty funny himself. The best part he said, was he'd get stuck and just sit there while his buddies got him out. He said if they pissed him off, he'd just run into the trees and bury himself! LMAO!
