We got a taste of the cold we were in for in Denver on the drive. We thought -11º F was pretty bad but we hit -17º F or so on the way home.
We took a stop at Shoshone Falls in Twin Falls and had fun looking at all the frozen waterfalls and trying to break holes in a little frozen lake.
We did a little tennis shoe ice skating on a big patch of ice on one of the overlooks. Only a few crashes.
All in all the drive was nice. The kids had their endless supply of movies and Sarah and I had audio books.
