I snowboard. I used to ski when I was younger, but switched to snowboarding because my dad snowboards, it's easier for me personally, and they don't crash as bad. I lived in Colorado Springs, Colorado, USA at the time, so I had a bunch of snow resorts all around in the mountains, like Vail, Breckenridge, Keystone, Beaver Creek, etc. We snowboard a loot, but stopped once we moved to a more desert climate (not because of the climate). The only other places I know you can snowboard or ski would be around Colorado and Utah and such, and maybe Eastern USA too, and if you live in the Northern hemisphere and it's summer, you can snowboard down in South America in Argentina. I know they have some resorts there that I've been to (during their summer unfortunately). There are also a bunch of spots in Europe too, especially Finland, since I had a Finish friend who shreds as well.
Although, snowboarding or skiing isn't really a sport you should do nude. It's very unpractical.
