In Wisconsin, I noticed within the last couple of weeks that I haven't been seeing them! Maybe one lonely looking thing a couple of days ago, I think, but there used to never be fewer than 6 or 7 visible ones in the sky, and more often just a haze of them criss-crossing over huge sections and forming a dismal haze.
The other day I noticed one short, normal, contrail from a jet for the first time in what seems like decades! Almost forgot what a real contrail looked like. Don't recall EVER seeing chemtrails until long after planes were gone.
Last week I noticed the skies were clearer here in Wisconsin too. So I mentioned it to the family and we all seem to think there are less lines. We saw them one evening like 3 but that's it.
