The plane I was on stopped through American Samoa one time on my way to Australia. It was night and we never actually got off the plane but I can still claim to have been there.
Of course, I can claim I've been to New York City because I stopped at one of the airports long enough to switch planes on my way to England for a short vacation. Although, I've been to New York State for a couple of visits because I drove from Pennsylvania, I've never actually seen NYC except on television.
Then again, does driving straight through a state on a 48 hour road trip count as really seeing a state? I've been through a few states on a cross country trip where I shifted off with another driver, stopping only for food or gas. What do I remember about some of those states? Honestly, not much except the only music I could find at night in some places was country.
I do have plans to go back to American Samoa to really check it out. I also want to see more than just the airport in Germany. Two more things on my some day list.
