As a way of giving my precious briars time to rest, I'm getting some abhorred corn cobs tomorrow. First question: do you have to break them in, and if so, how long does it take? Second, is it true that they don't really need to rest like briars? Thirdly, do they burn out? Lastly, how do I keep people from throwing bricks at me for looking like a Huck Finn reject?
