Windy Flats

This is one small part of a huge wind farm in southern Washington.  I have seen more of these up here (and already in Oregon) than anywhere I have been in the US other than southern California.

When I was in Oklahoma City earlier this year I saw one of the plants which manufactures the blades.  I have passed trucks on the highway which were transporting them to their destination (one blade at a time).  The blades are almost long as two tractor trailers placed end to end (in North Carolina they call those transfer trucks).
