Took this picture, looking at the clouds. The jets spray something, then it spreads and then there are clouds. Hear about chem trails, but looking at these pictures, can tell they are there. Why that is all I was wondering. If anyone knows and can explain, would be great. However one thing to note, there was a plane in the air but it did not show up in this pic, guess it is my camera, plane or jet , have a scratchy throat today. Just wondering if anyone knows the answer.
