My cousin told me a story about a couple of old Dodge pickups a friend of his bought. My cousin was a veitnam vet so he had seen a few snakes before other than your common garter snake however when he was riding in the towed vehicle which he had to keep the his foot on the clutch pedal, he discovered he wasn't alone. He first saw one slither across the dash,,, then noticed one on the seat,, then a few more on the floor. Needless to say he took his foot off the clutch which forced the towing vehicle to slow down at which time he "bailed" out of the Dodge. Seems that particular make had a glove box under the seat. The glove box was a perfect place for them to hibernate. Gives me chills just thinking about it!
