Had a problem years ago with signs. Put a new one up with a warning that the sign was protected with a marking dye. Don't know who it was, but heard the report at 3:30 in the morning. I called the police and met them at the end of the driveway.
The officer was laughing. There was a silhouette where the car had pulled into my driveway. He said they would be on the lookout for it and laughed again.
