I saw one on my land in Virginia about 1994, but I've stopped talking about it because no one believes me. I was hunting with 2 guys who were brothers and by agreement if one of them got a deer I would stay on stand while they checked it in. I heard a shot, then heard them drive out and about 10 minutes later it came from the same direction. I had about 5 seconds on it from about 50 or 60 yards, wasn't even sure what it was till I went home and looked it up since we never even think about them in the east. First patch of color I thought it was a deer but no question - round head, pointy little ears and a tail like the rope at the movie theater. Must have been an old one with a white face. He came to a low spot - probably muddy - scooched his feet up and jumped across so he wouldn't leave a track. We even heard it the night before - sounded like someone being murdered down in the same draw. One guy jumped out of his chair and stood there going "What was that?" over and over. This was a guy who had camped and hunted in Virginia a lot more than me.
There were a rash of sightings around then - later the state admitted they had turned a dozen loose to control the deer on the Skyline Drive. They were supposed to be neutered and collared, but I didn't see a collar on this one. It is believed that rich people buy cubs and then turn them loose after the thing looks at them funny once or twice, but they're not supposed to do well since they never learned to hunt properly. This one looked like he was doing OK. The farmer gave me hell for not shooting it since people up and down the road had seen it too, but I was just astounded and not even 100% sure what it was. I think he knew he almost bought he farm. I let the hammer down on my muzzel-loader real quiet, but I was so excited I didn't pull the trigger when I put it back to the safety notch and it let out a crack I'm sure he heard. I got up to see if I could catch another glimpse of him but I knew I was never going to see that animal again.
