I'm not surprised, considering they did the same thing during the Gulf war.
Honestly, doesn't it ever occur to the average joe that cloud formations do not from X positions naturally? Usually if the wind blows in one direction, the clouds will take the shape of whatever the wind is going.
I've also noticed that the spraying gets more aggressive during cloudy days. They were laying them quite religiously a few days ago in Northeast Pennsylvania. I happened to look at the cloudy sky and every "pocket" or "gap" in the clouds had a chemtrail above it. (I'll have to take pictures next time) In addition, during cloudy days, they also seem place the chemtrails at a lower altitude.
