Two staggered planes in the lead.A larger plane coming up behind spraying something denser onto the chemtrail.There is never this amount of air traffic here and its been 2 days of it.A clear blue sky became a muted haze in just hours and I have a slight cough now.This flight path is directly over the big lake that supplies water to a nearby town of 20, 00 ish people.What in the f are they spraying us with?..Nova Scotia Canada
