I am too lazy to quote page 1 and I don't want to start a war. I would just point out that if you are in the USA, you are a north american. Even in the southern point of Texas.
Anyways, I use my gas grill to light a pile of wood chips on the far right side of the grill. I then turn the gas off and add soaked wood chips every once in a while. This may not be great for the grill but I don't really care. I only turn the gas back on if the coals go out, or if the temp gets below 200 or so.
Lately I have gotten lazy, and after 1/2 hour or so of intense smoking, I put the ribs(or brisket or whatever) in a covered pan and put it in the oven at 220 for however long to finish it.
I have 2 small kids and babysitting the temp for 12 hours just isn't an option anymore!
