My youngest brother is a sophmore out in bozeman and we have always went out a a few times a year to ski and sled. We are trying to get some trips together to do some backcountry skiing with the sleds. The best spot i have seen myself would be that small forest service cabin above West Yellowstone to the north. We have a big enclosed heated trailer and half dozen sleds. I figured someone has to know better areas to do this kind of stuff out there? We are all experienced sledders and skiers and have the gear to do it safely. Any ideas or recommendations where to go? Thanks
