You guys heard of this? A guy near me designed a sprinkler system that is a good idea if it works. It waters, fertilizes/pesticides and de-rusts select areas in the summer. In the winter, all areas are turned off except by the driveway. I'm not sure what chemical is pumped through, but it melts ice and snow! This is not my company but here's the site. www.sunsnowsprinkler.com. I wish it was my company. I think this guy is going to do well for himself. Hopefully he does so he can improve his website.
