The usual suspects will come on the site and scream that chemtrails are a conspiracy theory and these trails are nothing but condensation from passenger airplanes. Of course, with identical weather conditions two days ago at the exact same time, when I was driving the exact route, there was not a single trail in the sky.
On this perfectly sunny day, according to the National Weather Service, the entire sky is obscured by a murky haze, as the chemtrails spread whatever it is they are spreading for whatever purpose they have. Condensation disappears in minutes. It does not linger in the sky for an entire day.
