Many of us say, "That was the worst place in the world!" But really: How many of us truly have the authority to say that? Lee Abbamonte does. He's the youngest American to visit all 193 member nations of the United Nations, and he's well on his way to visiting all 324 on The Travelers’ Century Club list, which includes territories and unique destinations in addition to nations. (Lee expects to have 321 of the 324 countries checked off by the end of the year).
