The inner geek in me loved this place, probably because it is a the tech-hub of the world. Nonetheless, the atmosphere of San Franciso was great because it felt like LA (the people and culture, without being so geographically spreadout) and had the buzz of NYC (without being too busy and hectic). If I had to move to the USA, San Francisco would certainly be on my list.
Fisherman’s Wharf is a cool place to hang out, but it is very touristy. Parking is outrageous, with most places wanting US$45 or more a day. Try to park on the street or just use public transport. Some of the great things to do in San Francisco would be to check out the Golden Gate Bridge, Fisherman’s Wharf, hop on a trolley tram, and visit Golden Gate Park (hop on a segway if you can!).
