When I opened this thread, I didn't realize that there was a debate about whether chemtrails are good or bad; I made the assumption that they are bad.
I'm thinking that it would be a good idea going forward to have this thread for people people to document chemtrail activity where they live, and, assuming they're bad, what we might be able to do about it.
For the discussion about chemtrails being good or bad, I've started a new thread:
"Are Chemtrails Good or Bad?" I'm hoping people won't mind copying and pasting code and text from this thread to the new thread so that they can quote and reply.
