Hey Star.. I'm from Chicago too! However i go to the University of Iowa
here's a link to the UNC Chapel Hill Sororities.. take a look at each one and try to get a feel for them! Also, check out the national sites for each chapter! I can't speak of the chapters there (since i don't go there) but i'm sure they're all fabulous women and you'll find your place among them!
