It is not an uncommon thing to see the forecast stating "gusts to 60mph". The recent 75 was not common, but 50 to 60 happens about 30 days a year. Our Building Code is for 90mph. Those wind speeds preclude anything bigger than the cup windmill I have which is around 4" or 5" diameter. The next bigger cup windmill was rated at 55mph max and that was only about 2" bigger in diameter. Dave
