Hope fish and game get a copy of this. Against state and federal laws to chase game from a motor vehicle.
I don't sense that the guy was really crowding the moose or harassing it, although the moose seem to think otherwise. I've followed moose down the road in a truck and on motorcycles trying to unnerve them enough so that they will get off the road so I can continue. I've always kept a good distance between me and the moose and tried to be patient because it can take a long time for moose to get the idea. If you don't put a little pressure on them, moose will stand there and stare at you all day long.
