I was considering posting something about this so glad you did... My friend and I are driving up to the KY-TENN border on Wed and then doing the yard sale down to Gadsden, AL.
I, too, am hoping for some super quilty finds.
Last year we started at Gadsden and got as far as Chattanooga. Ya don't get far. The traffic is horrendous. And it's pretty hot too. But we had a blast.
