Just out of interest: how many Americans on here own passports?
I've been an avid traveler for a while now, lived in Australia for a year, New Zealand for a year, spent a year in Thailand and visited Myanmar, Singapore, Malaysia, Cambodia, Vietnam, Laos, China, Taiwan, Japan, and spent a few holidays in Fiji, Cook Islands, Tahiti.
I moved around a lot growing up, from the mid-west, south, east coast and now west coast so I think it was just natural for me to want to see other parts of the world.
