Worked for 4 years in SF and left a couple years ago for another job... the whole time I was there I felt like I was seeing a different city than everyone else. For the most part I found it dirty, unfriendly, cold and way overpriced. There are some nice attractions and scenery but the day to day experience drove me nuts after a while. I also got tired of seeing my earnings slowly eaten up by all miscellaneous costs that go along with city living - paying for a parking spot, bridge tolls, extra taxes, etc. will not be missed
