Good news and bad news...
1. Tri-care is a piece of cake in the NW Atlanta metro area. 10 years ago, not so much but it is nice now. You won't have any problems finding docs. I am retired and my primary care is the off base.
2. Fort Mac and Gillem are both on the BRAC list and are closing - including the commissaries. Dobbins has a small AAFES but is pushing hard to have a comm. and a large expansion of the AAFES. Rumor has it, that the MILCON was approved but who knows.
3. NAS Atlanta (shares runway with Dobbins) is closing also and taking their clinic and pharmacy with them.
BTW, both the Army and the Navy have great facilities on Lake Allatoona to include cabins and campers. It can be a nice temporary place to hang out when you arrive.
