Well, maybe not quite.  Since our last card about Rugby a few years ago (see 10135015), someone did some re-measuring.  One online entry says “pinpointed the geographic center of North America to be in North Dakota’s Pierce County, about 16 miles southwest of Rugby, 5.2 miles north of Orrin, and 6 miles west of Balta,” so there you go.  Unused “local” card.  Grade: 1
