Things that I have noticed about Big Sky:

1. Helmets. Compared to other places I've skied, many more people are wearing helmets. Especially compared to Canada. It's probably 70-percent helmets.
2. It's cold. The sun is shining, and it doesn't seem to make any difference.
3. There is nothing on the mountain. No restaurant. No place to stop and get warm. Barely any bathrooms.
4. The runs are really, really wide.
5. There is no one here. Yesterday was a beautiful Saturday in the high season, and it wasn't crowded at all.
