55° ? and the air is starting to move.
I forgot about AZ not going along with the time change. Wendover NV is the border casino town that SLC residents come to every weekend to pay their "NV taxes" (gamble). Used to be the pacific to mountain time zone change was at the border, but I think it was about ten years ago they moved the time zone change about 5 miles West of town to end confusion with the time in town. Even the cell phone doesn't change until you're at the new time zone line.
I think our biggest hang up in Yellowstone was trying to get lunch, which took almost two hours before we were served. I did enjoy that ride over Beartooth at whatever close to midnight time it was. I don't remember it snowing tho.
