Well I would have gone Alpha Chi if I wasn't a Pi Phi. On my campus they are a great bunch of girls and a lot of my friends are AXs. However, I'd also have to say Tri-Delt. My aunt was a Tri-Delt here many years ago, and sense then have lost their charter. I would have loved to have experienced what she did!
(But I would never, ever give up my experiences as a Pi Phi! Blue and Wine forever!)
