I'm pretty sure the farm across the road will plant lots of acres, they want to make lots of money, and it use to be a cash crop around here in places. The remains of it are still in the ditches 40+ years later, even after the extreme eradication programs. Have heard pollen can go for miles, and my outdoor still has a seed or two, even after searches as far as I can walk it.

But I've been told my tin foil hat is a little tight.
