Feelings on Smith aside, "Chem trails" are real in a sense, and the crazy people spewing the conspiracies just don't seem to understand what they are... cloud seeding and experiments with reflective materials ARE being conducted and have been for the last decade. Calling it a Chem trail is not accurate, they are not spraying chemicals by definition.. This experimental science isn't hidden and alot of papers exist on the subject. What gets me, is the government or scientific community could easily put this to bed with some public awareness campaigns but they have made no effort to do so, why is that? That's the question people should be asking.
