The last time we were in Yellowstone in 2005 the road to MAMMOTH HOT SPRINGS was closed so we were excited to see them again. The last time we saw them was on a trip in 1982. Our friends, the Kurtzs, and our family rented RVs and took a trip West. Yellowstone was one of our stops. The springs had a lot more water running during that time. If you look closely in a distance you can see our 5th wheel..
