Jimmt Carter was coming to Yellowstone. I was sent from Cheyenne to pickup a communications satellite dish to be installed on a nearby mountain. Coming out of Montana, I entered the park from the north. In the northern part of the park ....I noticed a group of tourists parked, out of their cars and watching one woman going closer and closer to a Bull Moose munching on soemthing knee deep in a pond ....I got out and sat on the hood of my car to watch. I cautioned her to not take another step ...."The hair on his back just stood up, he's warning you not to take another step." Too late, she took the step......People were leaping into cars, it didn't matter if it was their car or not ....He had targeted the woman and her camera.....That animal smashed into the car she went into ....then launched again ....Proving his point, he turned and went bak to the exact same place he was before he charged.....The side of that car was heavily damaged .....The owner said "No problem, the park will take care of the damage." I countered with ....."You should read before leaving the entrance .....this one is soley on you."
