Well my stupid ass friends (they snowboard) just researched putting a halfpipe on the roof of their school (it's already the perfect shape and perfect slope) but the school district wants them to have insurance for at least 2 million dollars worth of damage and they want $5000us up front if they want to film it plus $1000us more per instance that they do anything like piss on the school and stuff like that.
When they told me that I almost shit myself. Kinda gives you a new respect for how much money is thrown around when these ski companies make a movie with something like that in it...
