Atlanta has plenty of riding opps. Nothing better than bombing down Peachtree (towards Buckhead) next to the cars doing 30!
At any rate, I did my undergrad at Tech and was one of the original guys on the team. Try joining up with them. There's also plenty of riding if you can find a way out of Atlanta. I know because we had to sponsor a few races, and I there are roads out somewhere not too far away.
Also, there's what's called the airport ride, leaving out of downtown atlanta and out towards the airport and back, maybe 50 or so miles total. Not a bad ride and a good way to find new areas.
again, start with the Tech team, visit a few shops and you'll be riding in no time.
ahh i miss the big atl.
