Been following your C-code Adventures here, 'chef.
I really like the simple creativity here, of using the secondary grate as a drip pan holder (why the eff have I never thought of that ... ?) and then, "PSB-like," adding the smoked beef to the veggies. Sly!
I have a question or 2 about the setup. No water pan, correct? Also, what's the coffee can-like thing for, down there?
