Centers, By Bubbler GPS

Centres de pistes de votre activité de Voyage près de 53 emplacements à travers les États-Unis

"Centers" are determined to be the geographic center of a state or land mass. The concept is based upon a 1964 study by the USGS where a location was determined to be the "balance point" of the land mass in question. This app allows you to claim centers across the country and track your progress online, and compare against others. More information on the project can be found on our website at http://Centers.BubblerGPS.com
