Another thought...

If Janie doesn't want to do Chattanooga,

Fri 10/21 I'll drive to Knoxville, see Roy's show, then camp with Occupy Knoxville.
Sat 10/22 I'd drive to Chattanooga and occupy Chattanooga until the show that night. Then drive home.
If I include Knoxville, I won't bother with Clemson... unless Janie's going.
