Thanks for the advice.

It worked well. They are very friendly and very happy that I called ahead
of time to get their opinion. They told me to ask to overfly Hartsfield at
5500 on the way down; however , go around under class B until I get north of
Hartsfield on the way back. They will be way too busy to get VFR traffic
identified and cleared to go over ATL before the plane gets into class B.
They don't want anyone circling and/or climbing to get over ATL after the
race. The area will be too conjested.
