A friend of mine had a barn like that.
People just seemed to like hitting his barn.
One day he took a backhoe and dug a trench that would stop a tank, 8 feet deep and 12 feet wide.
The wrecker only had to fish two totaled cars out of his “ditch” for people to get the idea.
A former friend of mine drove right into someone’s livingroom. Fortunately, no one was hurt. The driver was seriously effed up at the time. His wife packed up and moved out the very next day.
