My buds and I would go swimming off this enormous rock along the shoreline of the Springton reservoir (strictly verboten to swimming). The quite large reservoir was patrolled occasionally by an old man in a 12' aluminum boat with a 6hp outboard.
He would sometimes catch us and chase us out.
One day we had a load of cherry bombs and slingshots hoping he'd show up. Sure enough he arrives and tells us to get out. We got up to our clothes then started shooting the cherry bombs at him.
He got outta there quick.
Pretty stupid looking back, the gas tank could have blown up from a close hit.
