How many of you do this?? Is this something i should be aspiring too?? Whats the rush of doing that?? Has anyone ever wiped out from doing it? Is there a special trick to it? I saw one Chicky Poo do it and she had a special gizmo's on her throttle to keep her speed. Hmm. I just don't know how thrilling it would be to do that? Any thoughts on that trick?? And if so how many years experience or miles under their belt should a person have before they attempt it?
