Will,
As it turned out, we didn't get there either. We made it as far as the Tallapoosa River on 231, and saw traffic parked in both lanes for as far as we could see. I don't know if there was an accident or if that many other folks had the same idea, but either way, we made a U-turn and watched fireworks on TV. Oh well.
Looking forward to seeing you on the 12th,
Panda
