This came around a while back, and just now again. As I recall this is a professional photographer in a tundra buggy. Too close for comfort.
If the photographer goes missing, and the polar bear is sighted driving a stolen truck I think we can deduce what happened.
I reckon it's just a guy in a bear suit on his way to a Halloween party, he has to take the bus because his wife wouldn't drive him
"Give us a kiss" could easily have been added to the list of "famous last words".
