The onset date of chemtrails (or "persistent contrails") seem to vary by individual. If we can create a timeline of when the trails started for different locations, we can demonstrated if this is not simply a case of people noticing them as they increased in number. Please give at least the year in which you first noticed them, how long you have lived there, and as much additional information as you feel comfortable with.
The year should be the first year that you remember seeing the trails, or where you saw a large increase in the number of trails.
PLEASE ONLY TAKE THE SURVEY ONCE, TO KEEP THINGS ACCURATE. THANK YOU.
