Thanks that picture was taken by my wife at the St Louis ITCC. Petzl had put on a little competition that anyone could sine up for.
The object of the game was to walk around the table on 4x4s with out touching the ground, with a tie in point over the center of the table if you slipped of you scratched, it would be the other players turn, if not you could set up to take the shot, you could have you're feet on anything except the 4x4s, The side of table the fence or just suspended from the climbing line & lanyard it was all was fair game, before you made the shot you had to have two points of attachment.
After all of that you played pool by straight eight rules, after playing about seven or eight people I won The grand prizes of Petzl sequoia, 4 OK carabiner,1 Pantin Foot Ascender,Vertex Vent Helmet,12' grillon with CT rope clip,Caritool and a lg petzl swivel. So not bad for playing a few games of pool. WAY COOL!
