Hey alphaphichick20: I have the CD that Alpha Phi International sent with the complete Alpha Phi member directory. If you want, I'd be happy to check and see how many Phis are in the San Marcos area. I am sure there are a bunch, though how many are still in college, I don't know.
Have you ever thought about Texas Tech? They have an AWESOME A-Phi chapter there, right TechAPhi?
