Disneyland. I grew up in Anaheim, California and we could literally walk to Disneyland. No, really, you drove out of our street, turned right and Disneyland was right there. It's fair to say that we went quite a bit. I live in Colorado now, so I rarely get to go to Disneyland (only when we visit California on vacation), but I still *adore* it and seize every opportunity I get to go there.
If I ever ran away, I think I'd go to Disneyland.
