Snake! back yard.

I killed a 2 footer not long ago. I was tearing up plywood on a burned house and there it was lying on the floor insulation. I took the crow bar and killed it. I don't know what kind it was... it had diamond like markings down it's back. A fellow that looked at it said it was poisonous.

The snake you killed is a regular black snake. A king snake has a yellow ring around it's neck.

Hang it in a tree and it will start to rain. Old folk lore.
