jesus, reading all these squirrel stories is a shock to me. like finding out that the pillsbury doughboy is a psychopath. here in florida, squirrels are all cute and "tee hee." they will come only so close and then scurry away.
but when i lived in NYC, and would have lunch in Union Square park, the squirrels had a "New York attitude", they would come real close and stare me down, like sayin "You got sumpin fer me?" it took a while for them to get the hint. but still no wolverines like ya'll are describing.
