Matthew has been interested in dam's and how they work. So, we took a daytrip out to tour Grand Coulee Dam and then go swim in the huge lake that the dam creates. On a side note, one of Matt's favorite songs by Woody Guthrey is about Grand Coulee Dam - Roll on Columbia. Unfortunately, we didn't get very good pictures. But it was amazing to tour power house 3 (in the picture). It takes 2 years for staff to rebuild a turbine. They are huge. The tunnels that funnel the water to the turbines is as wide as 3 greyhound buses parked side by side. The whole thing is an amazing piece of engineering.
