After reading this, understand that when I mentioned poison ivy in the lb/pb how the shills came out hard against that post; now ask yourself why?
Here is how I figured this out with logical thinking and how I eventually got hard proofs.
Most people have lawn care who have machines to deal with leaves beyond most home owners. Being poor, I have no maintenance and have to crush my leaves to account for lazy neighbors. I have to be out there every few days due to few cans and the rate of pick up by sanitation.
Now think chem trails and crushing leaves every 2 or 3 days. I started to see a pattern that affected the toxicity of the newly fallen leaves on days that had the chem trail over cast.
