AF&G would likely consider that to be 'hazing of a game animal' and fine the operator, in this case the ski resort. Such tactics are illegal, most of the time, and since many of the regulations are a confusing maze, you could end up with all kinds of BS to sort through. OSHA might consider the groomer driver to have been 'exposed to a hazardous situation outside of  normal duties' and feel the need to throw around some fines. Much better to simply close the area down, get everyone out, and let BA Bullwinkle wander off.

Good pun though.
