Well, I totally disagree because the list includes Leaning Tower of Pisa, Time Square, Empire State Building ,Fontana de Trivi, to name just a few. To see and experience are the essence of sight-seeing, and hey are priceless!
Didn't realize that I visited 3/4 of these spots. I will add at least one more in Newfoundland, I forgot the name, but it is close to the west side of the island and it took millions of years in its formation!
