I did it two years (2006-2007) when I was working for the Atlanta Bicycle Campaign (now known at the Atlanta Bicycle Coalition). Can't remember if I've done it since -- maybe 2008.
It's a lot of fun if you have the day off. Thousands of cyclists from Decatur, Marietta, Roswell, south side of town (I think Epic Bikes gets a groups together), Gwinnett county, etc.
