Our "base" is Teton Village in the Jackson Hole area. We'd like to go to Cody to see the Buffalo Bill Historical Center. I know the distance is only about 117 miles or so (which here in Florida isn't far), but I realize distance is different in mountainous areas. Is this just too much to do in one day, i.e. would we spend most of our time sitting in the car? If it's an okay drive, what route is recommended (doesn't look like a big choice)? Also, what time is "dark" in early August? Thanks for any input!
