And if you get a chance, visit the Tetons and take a wildlife tour with the Teton Science School. They are doing wolf and bear adventures in Yellowstone I believe this year. Master's level wildlife folks, extremely knowledgeable about where the animals are, their habits, have safari-type vehicles and can tell you all about everything in the parks. We saw moose, elk, lots of bison, a black bear and a BLACK WOLF!! An amazing experience for we mid-westerners! Have a wonderful trip.
