I close the lid, get the temp up to 500 degrees.
Throw the chicken on and turn it down to medium heat (direct heat). Wait about 10 min and turn it at a right angle to make nice grill marks. Then leave it for another 10 min and flip it over. Cook some more, have a beer. Stick the thermometer in the fattest part and when it says 170 take it off and eat it. Don't open the lid too much to mess with it especially if it is thick like this one.
