actually, i really can't see the park service getting sued. it's not like there isn't a mongo fence there with signs all over saying
'do not go past the fence. people have died. if you go past the fence, you will probably die too. look, we're even using mutiple languages here, small words, and pictures! what? do we need to float skeletons down the river every 5 minutes for you to get the hint?'
or something like that...
