I don't know that I've ever heard of a campus that
didn't have more fraternities than sororities, but I'm also sure that I'll be corrected here if I'm wrong!
That said, I don't think Pitt should expand, Panhellenically. There are too many chapters not making quota, too many sororities that have thrown in the towel, to add another GLO. Over the years, I've seen so many good, strong groups somehow slip and go under when a shiny new colony starts up. I know that there are Pitt Advisors on GC - how many chapters have recolonized in the past 20 years? I can count seven (out of 11 sororities!), but maybe there's more?
Although, now that I've seen that there used to be Phi Mu and Zeta Tau Alpha at Pitt, I must admit that I'm intrigued...!!!
