Another member on t4r.org suggested I post here looking for leads on trails in MT as I'm headed from Vancouver, B.C. to Yellowstone Aug 5-10, taking the I-90. (I know the Big Sky overland rally is happening that weekend, but I won't have time to check it out.) Anyone have suggestions on some off-road / backroad trails that are worth checking out on the way there? I'm thinking of taking either the 191 or 89 south towards Yellowstone. I have some leads on Gallatin Canyon and Cooke City, though more details on Gallatin Canyon area is definitely welcome. If anyone is up for a trail run for a couple of hours and wants to take point, I'd be up for that as well. Thanks!
