I live in the Northeast, and yes, planes spray all the time. You can actually see them, then see the "contrails" spread out, and linger for hours. Sometimes very strange weather follows directly, and sometimes not, but the planes keep spraying. I've even seen planes either follow, or trail a black line in the sky. This has been going on here for over twenty years. I once observed a plane that apparently hung in the sky, stationary, for about an hour. One of the weirdest things I've ever seen.
