Well, I didn't believe in Chemtrails either really..
Although cloud seeding has been used in various places around the world for yrs.. This was done in Vietnam to flood the trails from the north, cause the failure of the Rice Crops etc etc.. So all this is not without precedent..
Never paid much attention to it.. But last yr, I saw the stuff happen right over my own backyard..
Not contrails, and definitely intentional..
Have vid and pics..
