Well, I looked for a cobra head at my feed store, but they have recently undergone some management changes (not in a good way) and have shrunk the garden tool section and brought in (of all things) plumbing parts, doorknobs, and other random items that belong in a hardware store. I asked the clerk how many doorknobs they sold and he agreed it was an odd choice. They also used to have really functional carts that one could load several bags of feed at waist height, but now have giant grocery type carts which I refuse to even use (I can get a bag of chicken feed IN the cart, but not OUT...) Anyway, no sign of a cobra weeder.
