Well, since there were only 2 nationals, AOII and AGD, we always did stuff with UNT. Especially with the fraternities. And depending on what houses meet quota will determine spring rush. I know that us and Alpha Gam almost always had a spring rush. Defenantly go to Meet the Greek night, it is a great chance to find out about the entire rush process and get an idea of what each house is about. Hope this helps, let me know if you have any more questions!
