After Bozeman I had a very, very long day on the way to Jackson, WY to stay with my college friend, Andy. Since Yellowstone is so huge, Andy made some suggestions about what I should try to see and do on the way south. I'm so glad I took his advice, because every single stop was well worth my time. This national park is a singular mashup of Mars and Eden that is really difficult to absorb. There were geysers, steaming sulfur waterfalls, enormous craggy mountains, snowbanks higher than my car, evergreens, sagebrush, cacti, bison, elk, and rabbits. I specifically made time for Mammoth Hot Springs and Grand Canyon of the Yellowstone, both of which were spectacular in completely different ways. There were a lot of tourists and some construction delays on the roads, so I was glad to be there in mid-May; I can't imagine navigating it in peak season, since I'm now spoiled by months of visiting national parks in the off-season. I stopped at Old Faithful and wandered around, but it wasn't set to go off for another couple of hours, and I needed to make tracks to Jackson, so I left it for the following day.
