The Most Complicated Tourist Attraction on Earth?

We recently traveled back home to New York City for an overdue visit with family and friends. While we were there we made it a priority to visit the National September 11 Memorial & Museum. We lived just two blocks from the Twin Towers of the World Trade Center on the day of the terrorist attack and like millions of other New Yorkers, US citizens and people around the world, that day changed our lives forever (including inspiring our Trans-Americas Journey).
