This summer we took a road trip to West Yellowstone. I think I went there every summer as a kid and James had never been, so off we went. We watched a documentary on old lodges in national parks before the trip and in honor of it, spent a couple hours on the patio of the Old Faithful Inn, waiting for the geyser to go. Lots of animals, all very close to us and lots of tourists, trying to get closer to the animals. I was positive we were going to see a buffalo gore someone a couple times, but rangers kept a good watch over the people. We did see BEARS, including two baby bears in fact, which I can't say I've really seen in the park before, at least not this close, even though it's known for them. As we were driving through the mountains, two cubs ran right in front of our car and we stopped in the middle of the road and took pictures of the momma bear eating a tree stump and the baby bears scampering up the hillside to her. It's a beautiful park with amazing geothermal features, worth a visit if you're nearby or passing through!
(tip: if you camp, opt for Canyon campground and avoid Bridge Bay and make your reservations way in advance.)
