Fair enough, your opinions are very reasonable. We don't all share the same governments so I'm sure it varies wildly around the globe as to what is being dumped into the sky and where.
I could believe that some tests are taking place in a few places both openly and covertly. It is the stance that there is a massive systemic bombardment happening everywhere, all the time and that every line in the sky as a chemtrail that I take issue with.
