They're there to see the Bluegrass Ridge Farm, the first commercial wind farm in Missouri. It's enormous, a commanding and surreal presence that changed the landscape of the northwest Missouri town. ...As the turbines' massive blades cut through the wind, it sounds a bit like a rumbling jet passing overhead. It's way more than Charlie Porter bargained for. Porter, who owns 20 acres in King City, has no turbines on his property but several near his home. Those turbines, he said, "have ruined our lives." "If you don't live underneath one of them and you drive down the highway, they look kind of neat," Porter said. "But for us, it's been a nightmare. They've ruined the equity in our home. The noise keeps us up at night. The shadows invade our home." Other concerns about wind farms include disruption to the land, visual blight and the risk they pose to birds.
