I would imagine at the bigger PAC-10 schools (UCLA, USC, UW, so on) that rush is big, especially sorority rush. At Stanford, we probably have the smallest greek system of any PAC-10 school (KKG, KAT, Pi Phi, Tri Delt, and AChiO I think) and that's it. We used to have DG and Alpha Phi but the administration is SO anti-Greek, that once a house leaves campus for any reason, it is pretty much impossible for them to get re-established. As for housing...FORGET IT!!! Stanford has a limit on greek housing (KA, KSig, Sigma Chi, SAE, Theta Delt, Phi Psi, Sigma Nu for the first time this fall, Thetas, and Tri Delts). There is also non housed Sig Ep, Delta Tau Delta, Dekes, and some other smaller Asian-American and predominately Jewish fraternities...Not a big greek school by any means...
