Real clay anywhere in the Southeast?

It always puzzles me that with the seeming abundance of red clay in the southest, particularly North Georgia, that no one seems to have installed red clay courts nearby. Does anybody know of any publically available red clay courts in the whole Southeast? I often travel to South Carolina, North Carolina, Alabama and Florida and would love to play on red clay - I play the synthetic green stuff all the time, but I'm told it's totally different.
