have you skied blue? it's generally a 50/50 shot of whether you stomp it and ride away unscathed, or stomp it and get escorted off the mountain with your pass in ski patrol's possession. if you don't land it, you can usually just tell them you suck and you messed up and didn't mean to go upside down.
It's funny to hear different stories about the invert policies of other mountains. Our insurance states that in order to prohibit inverts we would have to patrol the policy at ALL times in ALL areas of the mountain. Meaning if one jump wasn't being watched, the whole "no inverts" policy would be null and void as a defense to a law suit or anything like that. Therefore, we say "inverted maneuvers are not recommended".
