I grew up in Idaho, where irrigation is the reason why have lush lawns, trees, shrubs and a large agricultural industry. Otherwise, our high-desert natural landscape wouldn't be so lush. It wasn't until I was in my mid-20s on a cross-country drive that I even realized not all farming is dependent on such irrigation systems. I remember being in Nebraska and wondering where the irrigation pipes went to? These wheels and a motor in the middle make moving the pipeline fairly easy. Other pipes have to be moved by hand. Some irrigation systems divert water into small ditches between the crops, instead of sprinklers. When I was in high school, you could earn a nickel for every section of pipe moved when working on local farms.
