I have been so busy with Recruitment practice this week, I hadn't even realized that I was being talked about!
Yes, I am a Phi Mu at UNC-Greensboro. But I went to Carolina my freshman year! I actually attended two or three COB events with Delta Zeta, but by that time, I was fairly certain that I was transferring. I also was close friends with two girls in high school who are now Zetas at Carolina.
From what I know, the UNC Chapel Hill rush experience is competitive but not overwhelmingly so like many SEC-style rushes. I wish there was someone from UNC on the board who could give more info. I know that Phi Mu left the campus in 2001 or 2002, and Delta Zeta left this year. This would lead me to believe that their numbers are decreasing, but like I said, I don't have any complete information. It's really sad that DZ left... their house was so new and beautiful! There is tons of information on recruitment on their Panhellenic website, so that's definitely helpful.
One thing for out-of-state rushees at Carolina to remember- just because the rush isn't HIGHLY competitive doesn't mean that Southern standards don't apply! If you're in this situation, please read up on the dressing and ettiquette advice offered in other Southern rush threads.
