I'm going to poconos this weekend and never used my Weber smokey mountain as anything but a smoker. I want to take just the top and bottom part to use as a grill. I want to Try to grill chicken breast and maybe boil a pot of water on the bottom section of the wsm..I've never cooked over charcoal so close to the food, any tips and how long would chicken breast usually take to cook being only a couple inches above the charcoal? I will not be using the big middle section, just bottom and top for the lid.
