From Grand Teton National Park, we headed up
to Yellowstone. I didn't expect the park to be so big.
One of our forst stops was Old Faithful. The eruptions
were highlighted by the fact that it was below
freezing. There are a series of hot pools and geysers
within a mile hike of Old Faithful. The trail was, for the
most part, downhill from here. I was impressed that my folks
made the hike. It was worth it!
