Boy! You drive fast. It's about 210 miles from Byron to your town. It may take 1 hour just get through Atlanta - major construction going.
I wouldn't go through downtown Atlanta, unless you just want to. Just take I-75 South to I-285 West and follow it around, pick back up on I-75 on the south side of Atlanta. It'll add about 5 miles to your trip, but I can almost guarantee it'll be quicker, I-285 should be smooth sailing at that time on a Saturday morning.
Been working lately and haven't been able to get up with anybody to make any plans as of yet, got a couple of locations picked out, just got to get up with the right people. As soon as I know something, I'll post it here on the board....
