The University of Mississippi has a Kappa Alpha Order Chapter, Alpha Upsilon chapter founded in 1900. They were also IFC Fraternity of the Year for 2003. They also have a Phi Mu Chapter here, Alpha Delta, and they were founded here in the 1920s I believe. Both are VERY STRONG and not going anywhere ever! Of course, I think your son should date an AOII....
