Lost and found

So I was outside doing a bit of yardwork this weekend and I walked behind the
shed in the backyard and sitting there on the ground, covered in a thin layer
of dried mud, tucked underneath the edge of the shed, is a sixteen pound
bowling ball engraved with the initials J.P.C.

Yeah.

So I carried it over to the hose and rinsed it off. Seems to be in working condition (for a bowling ball).
Still no idea why someone would want to keep their bowling ball outside under their shed.
