Belle Fourche, South Dakota
is the current Brahmasthan of the USA

The marker for the middle of the USA is on private land
20 miles north of the TheTriStateMuseum.com
which built a granite stone, but is not really the center.
The owner of the private land does not want tourists walking on his property, and it is not for sale.

President Eisenhower added Alaska and Hawaii to the USA
 

Alaskans and Hawaiians are Americans
