Fink that grill is gorgeous! And the chicken looks just as good.
My buddy has one of those fancy roasters, and he loves it. He had some trouble with headspace one time, though, and so he just took off the cooking grate and put the bird and the roasting rack right down on the coal grate. He said it worked really well, and crisped the skin up perfectly.
The same buddy-- who is a neighbor of mine, too-- gets meat from Polyface all the time, and he is kind enough to share it. The chickens aren't especially tasty, but the pork is crazy-good. His pork shoulder makes me weak in the knees. Oh, and the Polyface eggs are delicious-- and they only charge $3 per dozen! The ground beef is really delicious too.
