nyl, bikelink gave me a lot of good information on group rides when I purchased my bike about a year ago. Most of their suggestions were things I found out on here first though. I ride in bluff park a lot and usually see a fair amount of cyclists while I'm out. I like riding Oak Mountain also. Usually I just keep an eye out for good riding areas with decent roads/traffic. I haven't gone on the group rides yet mainly because of a new child and all my bike friends bailed on me and sold their stuff. The dirtdog blog and cahaba seem to be a nice place to get listings of group rides though.
