SwimminFishie,
I graduated from a mid-size school in the south and will try to give you a bit of my knowledge. Keep an open mind. Do not drop or rush a sorority just because your friends do. Even though you might have grown up together and have the same interests, college is different. (You will grow apart and together at the same time), as that happens so will your interests. You can remain best friends, even if you are not in the same sorority. Treat Rush like a job interview, dress well, ask questions, be honest and above all be yourself. Get as many recs as possible for each sorority, even if you do not think you are interested in XYZ sorority. Recs give you a valuable introduction to ABC sorority and are required by most sororities to pledge. Talk to teachers, friends parents, contact the local alumnae chapter/panhellenic alumnae. Rush is a very exciting time, but the name says a lot about it. LSU has a very informative Greek Life website. Also, check out each organization's national website. You would not go to a job interview without knowing a little bit about the company and you did not chose LSU without checking the school out first. Please feel free to email me with any additional questions. Though I did not attend LSU, two of my sorority sisters transferred there and my college sweetheart attended LSU, so I know enough as they say "to be dangerous"
Enjoy your summer!!! Though no one can promise that you will pledge XYZ in August; I can tell you that if you keep an open mind, you will find the right place for you.
