Well, mine has been in the bucket for many years and is now through the planning stages and nearly ready for departure (Month or so). 16 days, from WV to Grand Tetons, Yellowstone, into Idaho, Montana via Beartooth Hwy, Big Horns, Devils Tower WY, 4 days in the Black Hills, Bad Lands, and back using as much two lane highway as allowable. Hopefully will be able to completely check that one off the list by the end of June.
PS; anyone feels froggy and would like to do this, I plan on camping most the way, unless weather dictates different, 4 days in a camping cabin in Rapid City (Starting Day 8) and then camping on the way back to WV. A friend of mine is riding down from Boston to join me. If you are interested, PM me and we'll chat.
