so we bought/closed on our house sept. 15th last fall, and the previous owner before us had snakes....friggen hate them....with a passion...I kill every garden snake I see. so at the closing I asked the owner...you took your snakes with you right? he laughed and said yup. this morning my wife and I were raking an area between 3 trees to make a nice spot for 2 hammocks and she screamed (like always) I looked down and saw this snake......I grabbed a shovel and killed it. what kind of snake is it? is it a pet snake?
