With a snake, always assume the worst. Our neighbor (a Man) is deathly afraid of snakes and called my husband to get it out from under his wife's jeep. Said it was a black snake. My husband is from Elk County and rattle snake hunts were something he did every year as a kid. Alan went up & when he went to reach under the jeep it rattled. He jumped back & asked Mike if he was trying to kill him. They moved the jeep and shot the snake. It was a rattler. Not common here BUT Mike is a gas well operator and the snakes have been known to climb into the trucks & rigs to get warm and ride back to other areas.
