I-25 North to downtown Cheyenne, where I stopped for lunch. From there it was back to the interstate and US-18 into South Dakota.
Brad and I entered northwest Wyoming on US-89, then followed Grand Loop Road through Yellowstone – the world’s first national park. We saw a bear walking in the wilderness, elk grazing near the Visitors Center, Yellowstone River, a waterfall, and numerous geysers (including Old Faithful).
We left Yellowstone on US-191 toward Grand Teton National Park, then US-14. We travelled the Tetons at night during a heavy rainstorm, so our only sightseeing at this point was of headlights and windshield wipers.
