Fort Benning

Fort Benning is a military army base 125 miles away from the city of Atlanta. It is first mentioned by Shane to Rick and the other survivors that the army base is a better choice over the CDC for shelter and to seek refuge there in Wildfire. However, the survivors chose to first go to the CDC but after finding a "dead end" there, the survivors decided to head towards Fort Benning Military Base.

Location
After the destruction of the CDC, the survivors may actually make it to the army base as military helicopters were seen flying towards what may be this army base in the video preview for Season 2, however this has yet to be confirmed.

Trivia

 * It was mentioned by Glenn when he looked at the map at the CDC, that Fort Benning was exactly 125 miles away from Atlanta.
