No RV's over the dam? Shit it's a long way around.
Nice pictures, although you left out the obligatory shot of the tailraces.
The labyrinth of tunnels, pipes and passages is quite amazing. I've seen the History Channel show on the building as least 20 times, and still sit enthralled when it comes on.
I had a chance to climb down into the swirl cage the turbine sits in (below the generator) at Grand Coulee Dam. Amazing.
