Pet peeve at the local track - pit parking

My favorite pit parking issue was when my friend put cones at each end where he parked the car. Went to staging, came back and a car is parked in the spot. Easily solved.

He grabbed keys to a friends diesel PU and pushed it out of the way. The look on the persons face when they came back was great.

Pit parking at some places, especially on stuff like street legal day is ridiculous.
