Suggestions on traveling in Wyoming

I noticed that nobody talked about this, but if you are planning on going from Yellowstone/Grand Teton to northern Colorado, you might consider going out the south entrance of Grand Teton down to Dubois, there's a nice FS campground about 20 miles out of Dubois toward Grand Teton where you could park for a night. Then a trip down to Lander to Sleeping Bear RV Park. Stop for the night and take in Sinks Canyon where the river goes into a cavern and then re-surfaces about 1/4 mile downstream. Then up over the switchbacks and over to the South Pass highway, No. 28 and over to South Pass and Atlantic City (the towns) and then on down past Red Canyon with its beautiful red walls and contrasting greenery and views of over 100 miles toward the north. You can also go to see the Mormon, Pony Express and Oregon Trails in a very historic part of the Westward expansion. After that, it's a short hop down to Rawlins and into northern Colorado.
