How many have you done?
What would a map of the world look like if it was created by tourists?
Vouchercloud, a U.K.-based travel deals site, has the answer, and it may or may not surprise you. The site used data from TripAdvisor's "Things to Do" rankings, and pulled the number one attraction for every country in the world.
The winner in the U.S.? New York City's Central Park. (As a New Yorker who lives just a few blocks from Central Park, I can certainly appreciate this pick. But the best place in the entire United States of America? I'm not so sure.)
Whether you agree with the picks or not (spoiler: you probably won't), it's fun to go through and see how many you've visited.
