Hiker/biker sites are the best thing since sliced bread. A lot of the campgrounds fill up before 9 a.m., so these make it possible to camp in the Tetons and Yellowstone.
Our food is stowed in a bear box and we are safely hidden from the bears!
(Melissa tried to fit inside the bear box for the night, but she couldn't fit . . . so she is reluctantly sleeping in the tent.)
