What are the biggest chapters?

[Pretty.in.Pink]

I know Phi Mu is obviously great everywhere because I love Phi Mu - I wasn't asking for the "elite" chapters per say.

I really just meant, which chapters are the most prominent but not necessary the largest. I was simply curious at which colleges Phi Mu is very firmly rooted in the system, as in where (at what schools) is it the oldest or most respected chapter?

I didn't mean anything harmful by my question. I don't believe in sorority "ranking" or "top tier/bottom tier" silliness.
