Before leaving for China, we had reserved a small cabin in Yellowstone National Park to celebrate Steven's tenth birthday. On our way back to Tennessee, we stopped there - driving our station wagon which by then had an air conditioner, installed at the beginning of our trip in Knoxville, Tennessee. We stopped at the Yellowstone River Water Fall and everyone took a picture there. We walked around the whole area. It was a very good experience for all of us, individually and as a group. Both of our children were at a great age to appreciate the beauty and the natural wonder before their eyes.
