I wonder how many cameras Abbey would have had there to film the climb? My guess is that if he were to climb it (and it was illegal then) he would have made it more of a challenge....like climbing it chalkless, sit start, by the moonlight.
Really, beyond the repercussions this may have on climbing access in Arches, doing an illegal climb, filming it, and publicizing it is just stupid...unless you're above the law.
Reminds me of a TR on this board
