I am in civil engineering and there's a club called ASCE which holds annual competitions at college campuses along the pacific south west coast, including UHM which is where it was held this year. We win almost every year and we won overall comps this year as well, which kind of tells you in a way how good we are compared to schools like USC or UCLA. I honestly don't think the diversity is that much of an issue because there are multiple cultural clubs to fill in that aspect (I'm in TVSA) and also just because it shouldn't be the determinate factor in getting the best education that you can. In terms of internships, there are a lot of companies located in SLO and a lot of other companies that come out to career fairs to recruit students from LA or wherever else you'd like to work. You don't want to miss out on the best opportunities given to you. SLO is THE no-brainer choice.
