Sorry I just don't weed as an issue that matters. Do I think we should put the seeds into clay balls and drop them everywhere to change the culture? No its the stupidest thing I have ever heard and I'm stoned out of my mind right now. Still it sounds stupid. Let me take another toke and then see. Nope still seems silly.
Better to use any resources to seed hillside with fast growing ground covers to stop landslides, or reforresting fire areas etc etc. I just don't see the weed across America as being important!
