"Oklahoma, where the wind comes sweeping down the plain" is not just a line in a song, it is real. Of course, I have lived in Colorado, Chicago, Minnesota, and Michigan, and find that no matter where you are, the wind is always the greatest just after you fill up the tank. I will concede to both Wyoming and North Dakota though... You guy's need to plant a bunch of trees on the western side of the state to slow it down!
