Yellowstone and Grand Teton National Parks.
We zoomed through Yellowstone on a coach and unfortunately it never stopped when we saw herds of bison or elk. We never did see any bear or wolves a disappointment nevertheless the landscape was awesome. We stayed near Old Faithful and watched it several times, Listening to presentations from the park rangers is always a favorite activity of mine. Grand Teton is breathtaking. Jackson Hole, is an okay tourist trap, with plenty of places to eat and drink.
