A few years ago, I accidentally turned on the TV on a Sunday afternoon and saw a building on Peachtree where I worked while in law school (a few blocks from the school itself).  I put the remote down.  Then I saw Freedom Parkway, and a dude on a horse trotting along side scores of abandoned cars.  It looked like the familiar scene I’d see every evening when driving home from work (other than the cop on a horse), but something was different…oh yes, there were zombies shuffling…
