I forgot to mention two of the amazing sights we saw. Between Geyser and Belt we were passed by a Google truck. The camera didn't seem to be spinning as it does on some videos I've seen, so I don't know if we will be on the route.
Roy and I sheltered in the only shade we could find. It was next to train tracks, and a trainload of train track repair equipment went by. We have seen a lot of track repairs on this trip, but we hadn't thought about how the equipment got to the repair site.
