I know of a group, I'd like to see at Iowa. :D

You were my first thought. And back before time began Phi Mu was 2 doors down from Alpha Xi. They could never turn that house into a sorority house now, wouldn't be nearly big enough, and couldn't tear it down because the street is on the historic register. But I think there are a few houses that could be made available; should the city decide to play nice that is. There are a BUNCH of rules, in particular parking, that make building a house pretty expensive. But A Chi O did it after their terrible tornado disaster. I was actually kind of surprised that a few chapters didn't rebuild to keep up.
