San Jose, California
It used to be a small unremarkable suburb of San Francisco. Now it is a big, overbuilt, congested, and still unremarkable suburb of San Francisco. I think San Jose wanted to be like LA.
When I go back to San Jose I feel a sense of nostalgia since I grew up there. Sometimes I miss it, but when I visit San Jose I can't wait to get out. What a rat race it's become.
