alright, maybe i didnt read enough into it. if he was just being a jack@ss and going big, then yeah he's responsible.
i do think that 14 still warrants some kind of change, even if it's more supervision or kicking people like this out. they're obviously dangerous (as in reckless), even for others.
if all the injuries were simply due to stupidity then i'd say the jumps don't appear to be the problem.
and carvedog, when i was talking about assessment of the jumps, i was talking about basic physics... if you take the average kid that's just hitting normal speed, not tryin to go big, that the impact isn't going to be such that the kids are going to get severly injured. if they're building jumps that are going to give 40 ft vertical with a flat landing at a normal speed without even trying, then that's a problem.
