I survived my trip (well back as far as great falls) and even saw a bear. I think it was a young black bear. it was a long way away, was small and I couldnt see mommy, so I didnt try to see anything more.
if you havent seen yellowstone, get on it. if you can, drive over the bearstooth pass to the northeast entrance, leaving you should go west, then north to the lewis and clark caverns. take the tour. $10 per person gets you an hour underground. great stuff to see.
