Oh man that sucks. Going on a trip and going big from the beginning is something we all do. Unfortunately, when you do that, this sort of thing happens frequently. We were sessioning a jump into soft snow we made at Mary Jane several years ago. A group from Iowa showed up and wanted to jump it. We told them to go for it. One guy was a little hesitant but wanted to do it. We told him no biggie just go slow. The jump was a roll in to a cat track with a steep ridge. So you could manage your speed. Dude hikes up and figure 11's it. Gets about a 20 ft drop, lands in the back seat and blows his acl. First run of the day, on the first day of his week long trip. Bummer. Sucks you are all laid up but at least you didn't do your knee.
