I am so sorry that Rush for you didn't have a happier ending. I have been following your story all along b/c my husband was an AKL there and one of my sorority sisters transferred there, but she had no Tri-Delts to affiliate with. I think you should DEFINITELY consider COB if they have it. If being greek, is important to you, then you owe it to yourself to see which houses will be participating. Your sorority search isn't over yet!
The more and more I am hearing at how rush has been going this fall, the more I am convinced that something is just not right. I was told that at my alma mater, girls were getting cut from almost every house after the first nite!
Best wishes to you, keep your chin up.
