After a REAL CLOSE EXAM it is a banded water snake.Are you sure its a rattler? Have one drying in my shop that some guys at work killed( i dont kill them myself) while yelling "COPPERHEAD, COPPERHEAD! but i think its a banded water snake. Most of the people i work with say they are afraid of 3 things. A live snake, a dead snake, and a stick that looks like a snake.
