It is only 80 miles, but Sunnyvale is a solid two hours drive, with typical traffic. Add rain or commute and it gets worse. Off hours and days it's only about an hour-twenty. Funny, when I lived in the city, I had friends who lived less than 20 miles away and it was a 2 hour commute for them on all the big arterial freeways!
Bloomingdales is the City Center (mall) right on market. Market Street cuts the city in half diagonally. All Muni trains/trams/streetcars go to Embarcadero (water front with the Ferry building) so if you get lost, that's a good way to get to a central spot for pick up, lol. SoMa (South of Market) is mostly industrial and businesses, Pier 39 and areas is tourist trap but with good views of the Golden Gate. Haight/Ashbury is the hippie hangout, Golden gate Park is HUGE, bigger than Central Park in NY. Tenderloin is the "low rent" district but is adjacent to premier Nob Hill, so the in between areas are still somewhat nice. It's called the Tender Knob, unofficially, lol! Oh, and cold there is in the high 40's.
Anyways, that should get you around pretty well, lol! It's my favorite city in the world, Chicago is a close second but only because it's cold as hell there! I don't do well in the cold...
Well, I have a camera I need to repair, then hopefully a test roll of film!
