What two campuses did we Pioneer? That's a hard one unless I go pull out my Path from Farmville, but I know that my chapter (Pi) I'm almost 99% positive was the first sorority on our campus. There may have been a local group, but I seriously doubt it.
(I'm sure we pioneered many more than this, but these are kind of the two biggies that no one else has yet)
*Alaska (Eta Zeta at University of Alaska Anchorage, and Zeta Mu at University of Alaska Fairbanks)
*Germany (Eta Mu)
Actually, Sigma was the first sorority on Murray State University's campus also. Our chapter is Alpha Chi chapter and we date back to 1942. Last Januray we celebrated our 60th anniversary of being on Murray's campus.
