I would totally dig to go to San Francisco!! It's the other bay area in the United States and the area in general is pretty much the headquarters for most (if not, all) things technology in the US as well.
Oh, and San Francisco weather is gorgeous for summertime, too.
I would love to live around San Diego as well, because the weather there is just amazing and it's like So-Cal with cool summer weather. Also, I'd like to live there just to be able to go to Comic Con without having to travel...
Oh, E3 would be a nice event to get to go to as well! I mean, as much as I am not into video games, I would just dig to get to go to a large convention and possibly meet some celebrities too, and to see what's new in the world of video games.
I'd love to live in California. One nice weather most of the time. Two celebrities everyone (particularly wouldn't mind meeting some Youtubers, I'm silly I know.) And Colorado sounds nice too. And Florida and Japan!
