Interesting sights.

Wendie and I had to make a trip to Sioux Falls SD on Aug 18. Saw and interesting sight on the way down.
It was a BNSF unit train of wind generator rotar blades. They used 3 flat cars for each pair of blades. It appeared to be a load of about 50 blades. They used an engine at each end.

In the same area coming back the next day right outside Jasper MN we found this great collection of wind machines.

Alternative energy I guess never really died, it is just evolving for the better.
