It's definitely not a bear. When it first turned about, I immediately thought it looked like an Ewok. Does that make me a geek?
I can't understand a Minnesotan driving down a road with his window down, considering the amount of heavy snow (and accompanying cold). To hear that scream might require an amazing auditory capacity, since the fellow would have had wind rushing in from the open window and the heaters going full blast (to prevent his lips and proboscis from freezing off).
And that's assuming he's not grooving to the radio while he drives.
I'd dearly love for Bigfoot to be legitimate, having grown up on all those great pseudo-documentaries the late-night channel used to show. This, however, is a guy in a suit.
