Mystic Cat-- I was responding to an earlier post wondering whether the religious background of Sewanee had anything to do with the women having locals!

Yeah, the Episcopalians would be about the *last* church to object to national Greeks!
A couple of years ago, there was a Sewanee woman on GC who was asking for help in colonizing a national there. I don't know if she's part of KD now or what but she said that she assumed that there was no particular reason why the girls had locals other than they'd started out that way and no one had made the move to nationals.
Possibly their administration has told them that they must go national, like mine did, due to liability concerns. I also know that they were heavily pursuing several women here but all of them told Sewanee that they would never consider a college that didn't have nationals. (Another reason why my college here is going after nationals--to be competitive.)
