ya you have to be 18. i was 17 over the 2006/2007 winter and tried gettin a spot in snowbird and they wouldnt let me. then this season i just missed the day the spots went on sale and couldnt find a way in. i heard that the bird sold out in like 2 1/2 hours or something like that this year? check out usfreeskiing.com for some stuff, and i know that some events, maybe all of them are ran by a company called MSI or something? they have links to it on usfreeskiings site.
