Hey guys, congrats on getting accepted to UCSF.
Im a D1 at UCSF and just wanted to give you some info to help you make your decision. I am from LA myself and dont find SF crowded at all. I even think that LA was much more crowded than here. During school, you really dont have time to go out and wont really get stuck in traffic because most probably you will be going to UCSF housing(close to campus, or a shuttle ride away). Anyways, this is as far as city goes.
The school itself is absolutely amazing, and I liked it alot. if you need more info message me and I might be able to help you out.
But dont forget, UCLA is great too. They just get less clinical training than we do. We are progressing really fast in pre clinic lab right now and my friends at UCLA just started doing some operative this quarter.
good luck
