I have been following the chemtrails stories for a while now and never knew what to think until it started happening in Chicago.
I also have noticed (out of hundreds of daily flights) there is a schedule: Usually 2 planes start out around 9:30 AM, and come out over Lake Michigan over the Chicago area, while others come from the opposite horizon from the west.
I have counted as many as 7 planes spraying simultaneously. Today, I reported this to an Illinois Congressman's office, Sydney Yates, and am waiting to hear back from them. The secretary said she would contact the Feds to find some answers. We'll see.
