Okay, true story... When I was on M60's in the reserves, we used to train at Truax Field in Madison WI where a Technical College is now located. One Saturday morning, we found a car parked in our training area (which used to be an air base) on an old driveway. We parked a tank on each side.
When we got out, and sat on the sponson boxes, we found there was a guy and his girlfriend inside of the car... both were quickly putting clothes back on... she was chewing him out but good for parking there.
The truck thingie made me think of that.
