I've been to Yellowstone and Jackson Hole on several occasions and it's amazing....working with the US Forest Service allowed me to get access to some areas that a lot of people will never get to see, it is beautiful and breath taking to say the least.....Jackson Hole can be crowded certain times of the year, but still worth going....I even got a chance to take a few deeps in some of the hot springs in Yellowstone.....by all means, respect the wildlife and everything it has to offer....
