Thanks for the input. I had a great trip riding at Valmont Bike Park in Boulder on the way up, then rode a lot of National Forest (?) trails around Teton Pass in Wyoming, and spent a couple of days at Targhee Resort, also in the Tetons. Spent one night each in Grand Teton and Yellowstone National Parks, then rode at Harriman State Park. That place had the only semi-flat terrain I rode over the whole trip, and was smooth and sandy, and of course , beautiful! I finished it off with an OTB crash over a cattle guard in Gunnison, Co. on the way home .(Had to crash at least once, even if it was .2 mi. from the end of the last ride of the trip.) Lots of happy trails, though! And the weather, OMG!
