The Hoover Dam tour itself is... well it's not Vegas lights at night by private helicopter while Jennifer Lawrence rubs your back and serves you expensive champagne in her shoe... It's run by government employees, some of whom are lazy slobs but I digress. Enough of them are jazzed about their jobs even after all these years. The scale of the project remains impressive, though the presentation, for instance the video, remains pedestrian.
What made this tour superb was the personability and knowledge of our guide/driver, Randy. The guy is a fountain of knowledge about the many aspects of the dam, the local flora & fauna (we saw bighorn sheep), & the history of Las Vegas and surrounding areas. His knowledge isn't superficial as you might expect from a tourguide. He's educated and seems to have local roots. I found myself repeating, "I never knew that." more than I had in many years.
The hummer was in good repair. It's a good looking ride with cold AC & Randy made sure we stayed hydrated and comfortable.
