It’s probably even bigger now. You know how sparsely populated Arkansas is. A person could drive for miles without seeing anything but trees and fields. I’d guess pot is a better cash crop than soy or cotton.
My dad once told me that a big time farmer took him way to the back of his farm and showed him a field of pot. He told my dad, “I can make more money off one acre of that than I can a hundred acres of soy beans.”
