I live in San Jose, California and just looked up some stats on it. It's supposedly the Capital of Silicon Valley but most of Silicon Valley is north of here.
Our biggest tourist attraction is probably the Winchester Mystery House. I grew up a mile away from it passed by it on the school bus all through high school then as an adult lived two blocks away and still never visited it.
We also have the Rosicrucion Museum and Plantarium which is a huge collection of Egyptian artifacts.
