Now it has been a year since I've been back but Montgomery is not en-route to Auburn from Atlanta.
Plus with no place to put anything cooler wise if I need a good stout beer I'll go someplace-Irish bread pub in Opelika had some good selections last time I was there and we are right down the street from there-Staying Getting raped at Holiday Inn express in Tiger Town.
Hopefully you'll see that change soon. Once they passed the 750ml law in the state and it went active last month, there has been a MASSIVE influx of good beer coming through. Unfortunately there isn't any Stone to be heard of (I still go to Nashville for occasional beer runs for all things Stone and Brooklyn), but there are some good ones starting to enter the state. Huntsville is the northern stronghold to find great stuff, but slowly I think it's working the way through the state. Rogue Double Chocolate Stout, Founders Breakfast Stout, the Terrapin stuff (MooHoo & Wake N Bake), Bell's Expedition & Kalamazoo stout.. some of those are starting to pop up here and there (if stouts are your thing). Straight to Ale is making some incredible stuff, but it's one local to up here and starting to work its way down to Birmingham. I'm hoping that all this stuff will be available soon for purchase in Auburn as well, if it isn't already.
Then again, if you're in Atlanta, you probably have a much better selection than we do here
Dogfish Head is one that immediately comes to mind
