I've seen a lot in my many years of traveling, some in various parts of the world and some that are not tourist attractions, but I have to admit I've seen the Niagara falls three times and they were breath taking all three times. The sense of power is outstanding! Those and the Grand Canyon are my favorite places in North America that nature has created. And strangely to some, diving in the ocean off the coast of Cuba is another favorite place of mine. PJ
