Yellowstone: what's the big deal about it?

Yellowstone is one of my favorite places. First off I love wildlife and photography, so Yellowstone is perfect for that. We are also hikers so, again, Yellowstone is perfect for that. But it you want a couple awesome things that you do not have to hike to a couple of my favorites are 1). The brink of the waterfalls. Being right at the place that all that water goes over the falls is amazing. The power of the water is unbelievable. If you have never been within a few feet of a powerful brink, it would amaze you. 2). Also the boiling river is also a great way to spend some time. It is where geo thermal water enters the river, so you can pick and chose the temp of water you want. Very relaxing, and fun. 3). As for the geysers, I like the middle geyers the best. The prismatic lake is incredible. We always get to the park between 5 and 6 am for the best animal viewing, and the fewest crowds. Last time there I watched a mama bear and her two cubs playing. I got some great photos of it.
