>>93488Yellowstone's cool to see if you've never done it before. Head to Cooke City for lunch, then make a quick trip up Daisy Pass. Pretty cool area back there. Pic related.
TONS of kickass singletrack around Darby, but that'd be a long-ass hike if you're on foot. Hell, it's a long-ass day on a moto.
Island Park and West Yellowstone have some kickass snowmobiling.
