BTW, sure, there are roads where traffic bunches up, but it's not that bad. I lived in Atlanta for 10 months up 75 in Kennesaw. My apartment was 11 miles from my office, at the top of 285 on West Paces Ferry. It took me no less than an hour, and that's in perfect conditions. THAT sucked.
As for Augusta's size, there are about 650,000 people around the CSRA.
