My Dad is really into snowmobiling. I know I know, Nevada isn't the place you think about snow. But the Ruby Mountains by Elko, NV has some pretty extreme snowmobiling. My Dad loves high marking and coming off huge cornices. He has a 2001 Yamaha (He only rides this one when the Polaris is broke, lol) and a 2002 Polaris 800, heavily modified, 151 inch track. He's a small guy so he doesn't need a super long track. I don't like snowmobiling, scares the crap outta me.
