I live history and what the hoover dam stands for is amazing. I feel the hoover dam tours are too expensive for my personal interest. But if you like the hydro power etc and history it's probably well worth it. Just seeing this marvel and walking acrossed it, thinking about the men who lost their lives to help build it and that this project was brought to us in 1931 so there would be jobs is an amazing venture, especially for how they got all the materials there and constructed it for that time period.
