On page 23 it shows re-colonization efforts at Iowa State and University of Oregon. That is great news!
At one time, our chapter at Missouri State (formerly named Southwest Missouri State University) was a 120 man chapter and had built a massive chapter house. Then they went belly-up a few years later. That was in the mid-1990's. Now they are coming back.
I'm happy were are going back to existing schools and not doing as many brand new starts. Best to go where there will be alumni support.
