For me, I wasn't even thinking about becoming a social greek in college...i literally wasn't thinking about it because APO took up SO MUCH TIME and energy. You would pretty much have to become inactive in APO at my school in order to be active in any other org. I would IMAGINE that it's hard to devote equal time to APO and a traditional frat in undergrad, especially if you were PLEDGED right in APO.
But I too, would like to hear more....i know nupe4life has a story.
