Yes, some of the photos are pretty good. However...
At least one of them is a good illustration of the stupidity of many tourists. See bear. Bear is wild animal. Unfortunately when bear attacks, as they do every year, bear gets put down, not dumb tourists. Sorry; but having lived in and around Yellowstone for several years, I lose patience with folks that do not respect the wild life. Taking photos from a car is one thing, getting out and approaching any wild animal is folly. Especially those with young (as in buffalo).
Have you ever seen someone trampled to death by a cow moose because they got between her and her calf? I have and it's not a pretty sight. I am not commenting about you personnally since I am assuming you stayed in your car. The shot of the bear "side show" got me a bit fired up. BTW, a couple of years ago, one of the workers at the lodge got trampled to death by a buffalo cow (with a calf) that she surprised while jogging early in the morning. My point is, they are wild animals and it is their home. Folks need to give them the space and respect they deserve.
Sorry for the rant. Nothing personal, just a pet peave.
Some of the photos are nice.
