For your benefit yr I flew out of Cowra for over 10 years, and I am quite familiar with the terrain between Cowra and Moruya. You would then be aware that the direct route would take you close enough to Crookwell, however I am interested in your theory of wind speed driving the turbines, such that the speed and turbulence behind would be any greater than the rotor turbulence created by the Wind and ridge alone without the interference of the turbines .... Do tell!
