Ya got me! Rugby is sometimes considered the "geographic center of North America" and there is a monument there, see below. Balta ND might contest that since they are officially closer.
In 1931, the town of Rugby erected a 15 feet (4.6 m) tall rock obelisk marking the "Geographical Center of North America". This was moved to a slightly different location in or after 1971. According to a listing by the U.S. Geological Survey, Rugby is actually approximately 15 miles (24 km) from the geographic center of North America [6 miles (9.7 km)] west of Balta), and even this designation carries no official status.
