On my first trip to New York City, I immediately turned my iPhone on upon landing (it was night outside) and had a very brief moment of panic that I had somehow boarded the wrong flight when the iPhone weather app said I was in "Jamaica".
SFO is also weird like that. It’s technically part of the city despite being physically separated from it. The first time I landed there I could see out the window as we were landing and I thought “this sure doesn’t like look San Francisco”.
