Grand Coulee Dam
This is the largest concrete structure in North America. It’s kind of amusing and kind of disappointing to see the conditionals people put on their superlatives: “tallest freestanding structure with largest functional structure east of the Mississippi” and such sound somewhat lame. Show me the tallest structure EVAR and I’ll be impressed. We came back up here after dinner to see the laser light show, and listened to the banter of the teenagers behind us. They seemed like quite decent kids. It was neat to think about the tiny community that built itself up here, and to be able to get up on this rock and see the whole dam town.
