DeltAlum,
Glad you liked it.
That probably is close though, cuz some schools have around 15%-20% and some schools are like around 50% I forget which was that high, but the tour guide (who could have been wrong) was like "its about half, so either join or don't, whatever, no big deal." Now, I realize that "half" could only mean 50% if you chose to belive in logic, but i'm not going to preach my religion to anyone.
Billy.
