A friend of mine (about 15 years ago, in south Alabama) kept having to replace his mail box and mail box post because some nearby former 'neighbors' were destroying it.
The destruction was retaliation for having a back-road closed off and sealed to prevent non-residents from racing thru the neighborhood at high speed, and using the neighborhood as a short cut from one County road to another.
Long story short, my friend (a Vietnam Vet) rigged a false base to the latest 'new' mailbox post, and beneath the surface was wired a military-grade artillery simulator submerged in a new can of yellow latex paint.
Sure enough, one Saturday night around 1:00 a.m. he and his wife and neighbors were awakened by the sound of a huge thud of an explosion.
Out front of the yard, there was the fallen mail box post, with a massive yellow paint explosion pattern, and a clean outline of where legs had been standing, along with a clean outline of where the perp's automobile had been parked and idling. The offenders had hauled-asss home.
The cops came, a report was filed, and my buddy rode out to the back County road with the Sheriff's Deputy, and to a trailer where he knew the offenders lived.
There they were, covered in yellow paint, and trying to get the paint off of their Oldsmobile 442.
The perps were arrested, and my buddy was issued a citation for reckless endangerment of morons.
He had to pay a $50 fine, which he gladly did the very next day.
The mailbox destroyers gave up and stayed the hell away.
