Funny thing about squirrels.
I actually enjoy the snot out of watching them, and pretty much never shoot them. I know it is contradictory, as I will shoot the nasty little burrowing ground squirrels, that the west has by the multi-millions, but the common tree variety, I have been known to feed.
With that said, for the guys who hunt them, and in areas where a tree rat is the eastern equivalent of a jackrabbit, I fully support them. But personally, I just like watching the funny little things, and at an old house, had one that eventually would take peanuts from my hand, or a small pile next to me on the porch.
