It was a longer drive then we have been doing, but we lucked out getting 7 nights in West Yellowstone at the last minute so we pushed it a bit, it was mostly freeway from SLC, except the last hundred miles. Once out of the SLC suburbs, it became very pretty country and even nicer once we hit the Idaho border. Only the last few miles of the trip were in Montana. The weather was perfect, and as we got closer to our destination, the view of the Grand Tetons was breathtaking. I think we will need to go there to get the full effect! Stay tuned.
