I used to own a Cessna 120. I flew out of an airport that had a part time (week-end) tower staffed by the National Guard. I used to ask to land in the grass short of the runway. They would always clear me but add that it was at my own risk. I always wanted to, but never did, ask "if I land on the asphalt is it at someone else's risk?"
Remember the one about the airliners lined up waiting to take off at some airport that I can't remember. (I always think of it as MCO, where the hold-short area is right along the expressway, separated by a chain-link fence.)
One of the aircraft came up on ground and reported, "Hey there's some ni**ers throwing rocks at the planes!". The tower called the next plane in line and asked for confirmation. "Yup, they's ni**ers all right."
