Visitors complained to hotel staff that the bears in Yellowstone weren't "trained" to come out and play.

While we can't confirm the validity or the seriousness of this comment card, some visitors to Yellowstone were apparently disappointed at the lack of wildlife sightings.

The card reads, "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 any bears."
