Have you noticed that they spray practically every day now? I live in the suburbs & that's what they do here.
Have you noticed that it seems that sometimes they quit spraying for a few days, after making a new batch?
Have you noticed that after making a batch, they start doing creepy things like parking near your house, sending out the phone-company / power-company workers to do unusual tasks right near your house...... ..... or that your phone starts acting funny, or that.... fill in the blanks. I look like a nut as it is :) LOL. I encourage people to make some, find out for themselves, & wake the hell up.
