OK, I'm not from Georgia (not many of us Atlanta people are) but I DO live in Atlanta. Downtown Atlanta even, by the zoo.
There was a CD party about a year ago (maybe 18 months ago) but I think it was culled from Diaper Pin, not MDC. I had some CDs for sale at a consignment sale at the time and one of the moms saw them and called me.
Heather Sanders is in Savannah or environs I think (maybe even Augusta). I know not Atlanta.
I would be interested in having a CD party, but you are right the traffic can be a bear. I had a CD mom from Marietta over about a month ago. If youlive east of Atlanta, Stone Mountain, Decatur, maybe even Lilburn or Snellville, there is a AP type group that meets weekly ( I think, it just doesn't fit into our schedule). Will look for their web site, PM me if you are interested. I know the moderator (?) is due with #2 in August (I think) so it may have slowed down.
Just let me know if you want to party, I'm always up for it!
