I just read the entire thread and I can't wait to follow what happens during the rest of rush!
I was a KA little sister at a small liberal arts D3 school, so greek life wasn't that big. However, KA has gotten better about contacting incoming freshman guys and hanging out during the summer months so that they can pick them up during fall rush. It worked out great last year! I went to a bigger school D-1AA my freshman year where I went through sorority recruitment and I remember hearing about summer rush for the guys down there. Sounds like maybe its similar to yours. Anyhow, can't wait to hear more!!
