19. The Stratosphere Tower
Have you ever heard the word “Insane”? Well, this is the best example befitting it. If you have the courage to hang of a skyscraper with nothing underneath but the air and the ground deep below than you are one of the heartiest persons in the world. You will be hanged 900 feet above Las Vegas while spinning in circles. If you have the fear of heights, you have the massive opportunity to overcome it.
