> I suspect from your post title that you are American. In the UK there is no such thing as a 'waiver'. You cannot sign away your right to sue. The registration process / document is proof that the Wall clearly advised you of the risks inherent when using a climbing wall. They will want to keep this information up to date, as it may be an important document in the event of a claim.
This is exactly right.
A number of years ago I worked weekends on a paintball site, whilst marshaling a tournament of some of the top teams and players in the UK a guy broke his leg. It was a bad break, his foot was next to his knee with bone sticking out of the skin.
Despite the wavier, morning brief and over 10 years experience playing paintball at competition level the judge ruled in his favour and he got paid out.
Apparently you should not be able to trip over a tree stump in a forest.
OK so that's a slight exaggeration, he was sliding in to a barricade when his leading foot hit a tree stump and stopped but his body didn't.
Recently a clay shooting ground that I go to was sued by an experienced shooter who was struck on the head by a bit of broken clay. Anyone who has ever shot a clay knows that sometimes the broken bits can be unpredictable hence this site having a poster up where you pay advising the use of glasses, a hat and ear plugs.
The guy only got a little ding on the head buy he got a payout.
I don't blame anywhere for not protecting because that is impossible but at least mitigating their liability in the event on an injury in an inherently dangerous activity.
