Nowadays, do-it-yourself construction work is a thing. Learning trades allows people to finish home improvement projects without having to pay high labor costs.
David Olson, a homeowner in Muskegon started a project in his backyard, only to discover it would take a lot of balls to complete it.
He started breaking up the concrete, and after he got most of the top slab removed, he started seeing what appeared to be spheres embedded in the sand underneath.
About 15 bowling balls were found buried in the ground. The number kept on going up. It was soon discovered that someone had buried 160 bowling balls under the house.
Why were they buried there? Nobody knows.
