One time while hunting with an old 12 ga. in Ohio, I had a grey squirrel climb down the trunk of the tree I was sititng under. It startled me, so I looked up and it freaked out, ran about 5 ft up the tree, and barked at me. It did so for over an hour, until dark. I was so frustrated I got up, turned, and blasted the dang thing from about 5-8 ft away. 12ga with 3 in Mag rifled slug. Oh yeah, by the way, the entire time it had half a corn cob in it's mouth, which the 1 1/4oz slug apparently turned into a grenade, as the entire squirrel vaporized. Literaly. Even the tail was in tiny, tiny, pieces. I was breathing squirrel. I was only about 15 at the time and know better now. Well, I knew better then, but I'm less hot headed now.
