Great ideas. thanks! We have been to Atlanta before for cousin/friends/business visits, and live in nearby NC so we are familiar with North Carolina red clay. Shout usually works with oxi-clean powder, but we may try Iron Out - it sounds intriguing!
We have one game per day except one day where we have 2 games. So will be nice to have some free time.
Thanks for the restaurant recommendations, I will start a list with your suggestions. We are foodies and love finding fun eats in the areas we travel.
