"An hour from Las Vegas, the world-famous Hoover Dam stands 726 feet high and stretches 1,244 feet wide — a monumental feat that took five years to complete and cost over 100 lives during construction; you can take a guided tour (I loved learning about the mechanics and the history) or a self-guided visit, explore the museum, and walk across the dam to take in the view (self-guided tours are $10 while guided tours are $30)." - Matthew Kepnes
