What does one do at 7am in Yellowstone in the snow?
1) Walk up and down steep hills to waterfalls
2) Bundle up and get as close to the boiling sulphur pots as possible
3) Search an open visitor center to obtain WARM coffee. This was nontrivial.
4) Stare at the Bison, white heron, (far away) bear, elk, etc populating the park.
5) Be amazed.
