I remember when the power went out during the Super Bowl years back, and it got me thinking. The Hoover Dam is right up the road from Las Vegas. With so much security at the Super Bowl, I hope there is equally as much at the Hoover Dam. If there was EVER a watch the water moment.... I hope they are really watching the Hoover Dam closely, because that would be a real problem if something ever happened to it.
I hope I am just being paranoid, but this is a hell of an upside down world right now.
That dam is 660 feet thick at its base, and 45 feet at crest. Short of medium nuke, there ain't a chance is hades it would even be cracked.
