What hasn't been mentioned yet is that there are very nice Forest Service campgrounds just West of U.S. 287, several with electric hookups. If you need a place to spend a night or two in fall during the leaf peeping season, just get off 287 at Ted's Place/CO 14 or Livermore/CR 74E and enjoy the scenery!
Once upon a time, U.S. 287 was the "National Parks Highway" that went from the Gulf of Mexico near Beaumont, TX to or through Rocky Mountain NP, Grand Teton NP, Yellowstone NP, and Glacier NP. We used it two days ago to return to Denver from Yellowstone via Lander and Rawlins, WY.
