That reminds me of when years ago I took my 73 Charger down to the gas station to get a soda. Pulled up to the door, put the tranny in Park, left the engine running. Went inside, bought my soda, go outside, and there's my Charger going in reverse in a big circle at idle speed. Wow, you talk about dropping the can of soda and running to the car to stop it!! Luckily the gas station had a real big parking lot, and lucky the wheels were turned - no damage to anything in the lot or my car. God does smile down on you sometimes!
