A Nitpick:
Why would Glenn and the other refugees head into downtown Atlanta to scavenge? It's pretty clear that their camp is out in the boonies, and Atlanta is surrounded by a vast suburban sprawl. To get downtown, the refugees would have to go past dozens of Wal-Mart's, Rite-Aid pharmacies, Sam's Clubs, grocery stores, etc. etc.
I figured they were just unfortunate souls trapped downtown, and it took me aback to realize they'd gone there voluntarily.
