Old Faithful through Bechler to the Yellowstone south entrance. 50 easy, fun miles.
30 miles on the Teton Crest. Best views ever.
50 miles through the heart of the Bob Marshall. Probably the single best backpack trip I've ever done.
80 miles on the Uinta Highline trail. If you start at Chepeta, you're cheating. Gotta start at Leidy Peak for actual bragging rights. Even then those who start farther east are the real heroes. The top of Porcupine Pass at sunrise is the most scenic view in all of Utah.
Many more to come.
