I drove past this thing and had to capture it. At first it appeared to be a long skinny airplane wing. After studying it a bit I realized that I was looking at a single blade from a wind turbine. It doesn't weigh that much, about 5,500 lbs, but is almost 200 ft long. It was manufactured in the US plant of a Spanish firm about 60 miles from where I found it. I suspect that they plan the route "very carefully."
