Harvey Nininger was eating a hamburger at a lunch counter in Sterling, Colorado, where he had placed a small stony meteorite beside his drink glass. A cattle truck driver sat at the counter beside Nininger and noticed the stone. After examining it he noted, "You know, my brother-in-law over in Nebraska may have one of these things in his yard. It's a big thing. He bumped into it when he was plowing several years ago in the field where there were no other rocks. He brought it up to the house and it's been lying in the yard ever since." First suspicious, Nininger gave one of his now-famous booklets to the driver to help him recognize meteorites, and he later received many fragments of the Potter meteorite fall.
