14 sororities participate in formal recruitment.
14 (open house - divided up over 2 days)
10 (sisterhood day)
6 (philanthropy)
3 (pref)
(Waaaaay back when, when I went through the process formerly known as "rush,"
there were 17 sororities. We did 17 split between 2 days, then 8, 5, 3. We also had lots of singing, cookies, skits, decorations...so different from the no frills recruitment now.)
