We drove over to West Yellowstone, to gather information about what to see in the park. We stopped and talked to one of the rangers. He gave us some good options for both Yellowstone and Teton National Parks, as well as, a couple of "must see" sights outside the parks. He also pointed out a great 4x4 road that takes you to a less-visited part of the park. I think we have decided to see both parks from our current location, instead of moving further south to see Teton NP.
We also picked up six geocaches today: two historical earthcaches and four traditional caches.
