Too bad there's not TEN stars! Simply amazing! The size and scale of Hoover Dam are incredible, especially when you figure someone had to determine WHERE to even put it!
We stayed an extra day in Las Vegas just to make the drive out here. You can walk around and see quite a bit - the sight of the overflows not-overflowing was pretty mind boggling but it has been years since the water level was high enough. To see how much the water level has dropped is quite remarkable.
Well worth the drive - we were planning to go on the tour but there was a 3 hour wait. It was the first day of spring break and there was quite a crowd. Great to see that we Americans still want to see this stuff!
