Yellowstone is one of my favorite National Parks. Thanks for reminding me of the beauty and uniqueness of it. I had somehow forgotten (mostly). Your images remind me that it's been too long since I've been out that way. I'll have to plan a trip soon. Thanks for the incredible photos of an amazing place.
My favorite part of the park was the wildlife. It was pretty incredible seeing entire herds of buffalo chilling in the road while all the tourists waited patiently for them to move. Those animals are so much larger than you realize from a photograph.
The bison are HUGE! The last time I went I was just driving through on a high school trip so my memories were pretty foggy - definitely a great reminder of how gorgeous it all actually is!
Did you get to see any wolves, bear, or moose? The wildlife is so neat out there, and they aren't very shy of people.
