Chemtrails? Contrails? No Wind Turbine Wake
The argument that persistent contrails can be created by airplanes has been a long and hard fight. Well this image proves that condensation trails that are persistent and fill in the area are INDEED possible from simple turbulence

I saw this in western Iowa on my last trip home. I-80 passes both north and south of some pretty extensive wind farms. The right temp, humidity, and wind to move those blades and it's almost like a self generating fog. It was pretty interesting to drive through and see the condensation formation trail the blades.
