Why go to Rock Springs when you can turn off at Rawlins, go north to Lander and then on to Dubois and up to Grand Teton on the way to Yellowstone. Or, get off at Cheyenne, go through Casper to Shoshoni and turn right to Thermopolis through the Wind River Canyon, up to Cody and over Sylvan Pass into the east entrance to Yellowstone. Lots to see once you get off I-80 once you get up to Dubois and over Togwotee Pass, where you first see the Tetons, which are majestic, and then up the John D. Rockefeller Parkway to the south entrance of Yellowstone and then only about 10-15 miles to Lewis Lake, just past Lewis Canyon. Then to Grant Village to the start of the loops. Right takes you to Yellowstone Lake and up to Canyon and over to Norris Junction and back to Old Faithful. If you keep going past Canyon over Dunraven Pass up to Mammoth and then back down to Norris, etc, Lots to see and keep youngsters interested.
