I did get to speak to Bill F., the one person I know who is in my professional life and in SF fandom. He stopped by to say he couldn't catch my presentation, as he needed to hear one in a concurrent session. Oh, well.
Anyway, I then hopped in the car and started back to Atlanta. Had to stop half-way for caffeine, as I was nodding over the wheel. Got shortly after 5, having had a miraculous speed-limit ride up the downtown connector circa 4:45 PM. Collapsed on the sofa until 6:30, when my wonderful sister-in-law delivered a plate of food. (I'd declined a supper invitation on the grounds of exhaustion and the need to quarantine my cold.) And now it's time for medicine and bed. Feels like I could sleep for 2 days..
