Yes, my scratchy throat is commonly associated with the trails.

Because they have received a lot of attention in the past year, I believe they have cut back on the volume of material that they spray. When I look carefully at the contrails I see every day from my office window, I can also see something that I've never seen, and I've been looking at the sky all of my life.

Now I see a thin residue that disperses more quickly but remains and looks different than normal contrails. It seems that they've lightened the amount of material being dispersed so the trails are much harder to see. They do this to avoid attention, obviously.

At any rate, there should be full accountability to those who have made this decision to experiment on humans:
