Years ago Nebraskans got tired of leaning into the wind having their top soil blown away and chickens laying their eggs two and three times. Seems the wind continually came down from Canada and there was nothing between Canada and Nebraska to stop it. The farmers all got together and decided to build a fence across the North Border of the State of Nebraska. . . . the idea being to stop that cold wind. It might've worked too. The barbed wire they used was strong enough .but the real problem was that a couple owners of farms on the upper boarder kept leaving their gates open.
