He is owned by Graham McCabe, managing director of the ski centre, who said: "Guinness is slightly mad and very cheeky, but also extremely clever."
Mr McCabe said: "He has actually figured out how to work the release mechanism and go up the mountain whenever he wants.
"He will hang on for a while and go up for as long as he feels like it. He either goes all the way to the top or gets bored and drops off into the snow and runs back down to get another one.
Though not very good at waiting his turn, Guinness is quite popular with skiers and snowboarders who visit the center. Link to story. Link to video. -via Arbroath
