lukaszthegreat: how long is your passport valid? ours are 10 years.
and what about actually leaving usa? don't you want to go to mexico brazil, france, thailand and so on and on?
world is a big place.
All passports are valid for 10 years.
Going places like that requires a lot of something I don't have: time and money. Sure, I'd love to visit places like that, but buying a passport now is not going to make a difference when I can't take the time off of work, can't afford the plane ticket to get there, can't afford the hotel once I've arrived, can't afford food to keep me alive while I'm there, etc., etc., etc.
Yes, the world is a big place, but so is the United States (almost as big as all of Europe) and I still haven't seen even a quarter of it. On top of that, nearly every country I would like to visit has been a part of building the US, so if I want to experience say, Brazilian culture, I'd go to West 46th Street in New York or south Florida, both a cheap plane flight or a long drive away from where I live.
