Going back a few years I can relate 2 true stories -
Guy I knew bought a property with the intent to flip it after a remodel. About 3 acres of land with a house and a barn. And a couple of junk cars. He arranges for someone to get the cars off the property only to find out there was another car buried under the others. So they dig that one up and find another. And another. And another.
In the end there were 15 vehicles buried in that spot.
And the same thing happened to a good friend of mine. Had a smaller 1/2 acre lot and wanted to build an Ohana (mother-in law unit). Got an excavator in to dig some underground utilities and they found 3 cars buried.
WOW! Same thing happened to a friend of mine.
He wanted to bury his mother in law, and an excavator dug up three of her ex-lovers (in their own cars).
BTW, his mother in law was still living (in his home).
