Regarding So Cal alumni, go to this site:
http://www.mcgeorge.edu/alumni_resources/alumni_at_a_glance.htmIt shows how many alumni are in each part of the state. Since I am only a 1L I have no idea about actually getting a job down there, but I do know that I'd say 25% of the people in my section are from So Cal and have internships lined up there for the summer...
Regarding housing, most people I know live on campus, but I am married so we wanted to live off campus. The on-campus housing is decent, affordable from what I hear. Outside of the campus, the neigborhood is...sketchy and there are not many students that live there. Most live about 5-10 minutes away.
I found housing on craigslist, but the Housing office at the school has lots of info on people who want to rent their apts/houses out to McGeorge students. The nice new apartment buildings are in the 'burbs, about 30 minutes away, but who want's to live there?
Regarding stuff to do, there are 2 art house cinemas in sac, so that's fun. Also every 2nd saturday they have the "Second Saturday Art Walk" where you go from gallery to gallery and they have free wine/appetizers. I haven't done that yet but it sounds like fun. Then on the 2nd sunday of each month they have an "antique fair" which is basically a big flea market, but with really good stuff. There are also lots of great restaurants in the downtown/midtown/east sac area...which is all only about 10 min. max from campus. Bar review, of course, on thursdays. Downtown is becoming more vibrant I think with lots of shops and places to hang out really coming into their own.
Beyond that, it's only 90 minutes to the bay and 2 hrs to Tahoe. My wife and I have gone to Monterey a few times (3 hrs)...
Anything more, just ask.
