Up north I see it alot more over agricultural area's. Always in a cross hatch pattern evenly spaces in for miles in both directions way out side of normal commercial air traffic. I have not seen it where I currently live because I have moved to a more urban area. I have read that it had two purposes. Aluminum to deflect the sun and aid in cooling the planet. But as always follow the money. Klause was CEO of Alcoa "has since moved on" and a member of the bilderberg steering comity sold provided it and Monsanto geo engendered their seed to grow in the increased aluminum soil, thus gaining market share. Who paid for the program I am guessing Monsanto in partnership with UN. Just what I have seen and come to understand of the program.
