I had noticed this phenomena two years ago, before a particularly virulent flu season that made headlines in Northwestern Indiana for reported cases of bronchitis and upper resperatory infections. I've been reading up on them and watching the skies ever since, but the spraying today was unprecedented. Feeling I had to do something, I stopped a woman walking her dog and pointed out the trails. Polite and interested, she claimed to have never noticed them. I told her I thought that something or someone was trying to poison us.
Contrails stop and start at edge of city.
Haven't seen them during the day, maybe because of the famous west Texas winds that blow harder in the daytime.
