Thanks, I did the 138 thing once for a short jaunt just to get the number on there. :-)

Knock on wood I keep pretty peeled and choose my areas for getting my laps back pretty carefully.
Leaving at 5AM both ways makes for the lightest traffic for the trip. Getting into Atlanta near lunch hour is a trip and I have to try and relax the rest of the way in.
I have been making the run a minimum 4 times a year since 1993 and always enjoy it.
