Found this little tidbit on the net:
"Then we stumble onto this complaint from a visitor to Yellowstone National Park. "Our visit was wonderful but we never saw any bears. Please train your bears to be where guests can see them. This was an expensive trip to not get to see bears." Seriously. We’re not making this up. Our only logical explanation is that all of Yellowstone’s certified bear trainers must have been called to emergency fire-fighting duty."
