My wife and some friends saw one come up behind me up at Crystal Mtn. We went to their big new years party, and I brought my snow disc. Bout 11:30 or so, I hiked up I think it is called Chair 9 run till I ran out of breath, gave a 'hey watch my dumb drunk @ss!!!' and sled down the hill. When I got to the bottom they were all frantic.... You didnt hear us yelling at you?!?!?! A big black dog came out of the brush behind you and was creeping up on you!!!! They said it was way bigger than a pet or coyote. Didnt bug me, I just wanted another beer.... The way I look at it, no wild animals pay attention to fences... They will run where ever their hearts desire or where the food is.
