Seems like this behavior would be well known for decades. If it is important to keep the Moose from hampering drivers from reaching their vehicles, why isn’t it standard practice to put bins of salt away from the parking areas so the moose will go there instead ?
All this advisory does is warn people not to try to push the moose away. So if the moose is taking an hour to lick salt off your car you are just supposed to wait until it leaves before approaching your car ? That’s a poor solution to a long-standing and well-known seasonal problem.
