GeekyP, what you ahve said is so true!
The mind set is get New Frosh Candidates so they can be there for 4/5 years.
The idea of getting more mature people to rush is:
They have a mind set for study.
Are a lot more mature.
Have a better idea for what they want.
Are more effecient to do things like hold and office, make grades, and participate in extracurricular activites.
What is funny, is that there is only maybe a 2 year spread between them.
