I don't really know anything about the USC Greek scene, but it's based there.

The author went to USC also? My school is just ALL over that Legally Blonde franchise. Reese spent a week at KKG (which could explain the KKG reference...?!) "Harvard" was really USC- all of the campus shots were on SC, including her "dorm" aka our auditorium. I saw the sequel being filmed last semester... I just saw BIG tour buses with DELTA NU and a big picture of Bruiser on the side. I haven't seen the movie, so I don't know what thats about. But both Reese and Luke were on campus filming.
I love going to school in LA. The best is when you see your actual sorority house in the movies.
