Dude, Southern California? Not many places in SoCal aren't extremely competitive. Drew/King is historically less competitive due to it's location and the dysfunctionality of the hospital. Plus, the hospital is in such poor financial shape that they are making noise about closure or partial closure. IMHO, they're not going to close the place, because then all the indigent patients that they see there go to other nearby hospitals who are already financially dodgy. Closing MLK would start the domino effect, by my way of seeing it.
Fresno/Kern is somewhat less competitive since it's out in the middle of nowhere. The program seems fine to me from what little I know of it, but it's not even truly SoCal. More like central valley/desert. The vast majority of the patient base represents the population, which is mostly agriculture-based. I hear they get some gnarly farm/industrial trauma though. Maricopa is the next nearest program to SoCal that I can think of, and it's pretty competitive. The NorCal programs, and Pac NW programs are all pretty darned competitive due to location as well.
edit: spelling. "Fresco". Geez.
