This flew low over our house today - and then turned back for another pass. We all rushed outside to see it, figured it was spraying, and rushed back inside. Turns out though it wasn't spraying an chemical insecticide, but rather a
harmless-to-humans bacteria that kills mosquito larvae. My tax dollars at work (the town pays to spray all of the wetlands), and quite frankly an awesome way to spend money - low-flying 'copters (reminded me of 'nam) and less mozzies - how great is that?
