I thought I would give a little advice. I'm starting there next fall, so I can't give any information regarding the medical school, but I did my undergrad there and I also currently work at the med center in sacramento, so I'm getting a taste of how it all works.
Location: Um, I'm originally from the SF area, but I've been living here for almost 6, wow, six years. In all honesty, I'm very excited to move after medical school, but I really can't complain. People are nice, bars are convenient, the atmosphere is cozy and it is VERY safe.
Rank: For those of you concerned with a rank, I mean honestly davis has such a comprehensive medical center. We're talking Children's Hospitals to NCI funded Cancer Institute, the MIND Institute, Ronald McDonald House, It just goes on and on. I feel like Davis is a mastermind underdog. Crazy research, amazing clinical care and education all come out of this massive facility. Not to mention affiliates. Davis works with the VA, Sutter, Mercy, Kaiser and many more (including Shriners). I honestly think the Sacramento campus is amazing and because it isn't the highest rank place, it keeps its modesty, therefore putting people above and beyond pride, money and fame.
Distance of med school to med center: I believe the campus will be ready in the Spring of 2006, which will be our second year. So basically two years in Davis, two years in Sac. That can be cool. I lived in both and I like them both. Davis is the safe haven, best for studying and being hardcore. Sac is like a little dangerous in the sense that there are good and bad parts. This means that you get to see crazy stuff in the ED!! It also has a great downtown area and is a great place to meet people for us single people out there.
Miscellaneous: Davis has a law school, vet school, education school, a business school among other amazing graduate studies programs. In addition, you have the undergrads, which always spice up the social scene. This is a great place to meet lifelong friends and to enjoy interests outside of medicine. Tahoe really is close and so is SF. In fact, I go to Tahoe like 4-5 times a year and I go to SF twice a month or so.
I hope that is useful to some that are wondering why they should or shouldn't come. I'm stoked to be beginning the most challenging and fun portion of my life next fall, who's comin wit me!
