When i was in high school, there was this house we ran by on the sidewalk and the guy would always yell at us to "Stay of his parking." One day we run by his house, and our whole team was running together and some were on the sidewalk and next thing I know a girl screams. We look over, and this guy is standing by his fence with a big knife and he put a trip wire from his fence to a tree that a kid fell over right after that. Our coach called the police and we never saw the guy again.
