After two full days of sightseeing, my wife and I planned to get across Washington State as quickly as we could. When we left Coeur d’Alene, I called my friend Bean so he could estimate the time of our arrival at his house in Seattle. Instead of urging us to get there as quickly as possible, he practically insisted that we take a detour to see the world’s largest concrete structure. I hated to inconvenience Bean by arriving at 1:00 a.m. but it was his idea. As he pointed out, my wife and I may never get another chance to see Grand Coulee Dam.
Exiting I-90 and taking U.S. Route 2 would add two hours to our trip across the state. It was well worth it. The dam is a marvel of human engineering. Even more impressive is the Grand Coulee, a work of nature’s engineering. The river bed was carved by glacial floods during the ice age.
