I personally have noticed over the past decade of watching these things that the areas being sprayed actually become WARMER in the aftermath of a major spray operation, not colder as many people expect. Maybe it's just me but that is what I have personally experienced.
PS, the shit being sprayed in highly refined Fly Ash, a toxic byproduct of the coal industry which contains arsenic, barium, beryllium, boron, cadmium, chromium, thallium, selenium, molybdenum, mercury, aluminum and more... all perfectly healthy elements for the human body (NOT...)!
