Okay, trying to figure out SF/Berkeley/PA from an e-distance is not as easy as I thought it would be. I've solicited a lot of useful advice from Cal people, but I still have a ways to go. I know that I ask a lot of questions, so please bear with me.
1. I feel so dumb for not copying and saving a lot of the useful comments I've already received about the trains to Cal. Basically, I'm landing at Oakland Airport way early in the late afternoon and I want to get up to Berkeley. Which train? Where will I have to wait? I want to avoid all questionable areas, since darkness will fall soon after I get there.
PS: how silly is it that Cal's website advises you using only car directions?
2. What is "must see" in Berkeley, besides the University? How do people get around in the city? Is it small? I'll be staying only a few blocks from Boalt, at a hostel. I wanted the
Graduate experience.

3. What is "must see" in SF and the surrounding area? Keep in mind that I don't own a car, I usually dislike walking for more than twenty blocks. In unrelated news, I like Thai and Vietnamese food.
3. How would I get down to Stanford? Is it worth it if I'll probably accept an offer of admission sight unseen? The guy at the Stanford UG Admissions department literally told me he would "advise against it unless [I'm] prepared to deal with a few trains and a LOT of delays." Would you advise Cal Train?
