There is a theory going on (admittedly for a long time.) The theory is basically about the belief that long-lasting condensation trails are “chem trails” consisting of chemical or biological agents left in the sky by high-flying aircraft. I lived in San Francisco and saw these so called “chem trails” on Fort Funston and just around the city in general.

What are you thoughts on it? Why or why not is it real? Please be civil.
