In McMinn County, TN, which is 30 miles north of Chattanooga, someone keeps throwing heavy objects off of overpasses onto Interstate 75.
In the latest incident, a tractor-trailer was hit by a mailbox that was still attached to its 4-by-4 wooden post. The trucker wasn’t hurt.
It was the third attack in the same area in a month and a half. The two other attacks involved a mailbox and an electric motor. And several years ago someone dropped a tombstone onto a car, seriously injuring a passenger.
