Jon, thanks for the tips. I just got my thermometer yesterday from New Braunfield. I checked it out today using and oven thermometer inside the cooking chamber on the grill. I found I had a 20 degree difference, and I rechecked it several times. Thanks for the help. I've got a party this Sunday for 15 people and I'm going to be smoking a turkey and 10lb. of ribs. New week, I'm going to try my first pork shoulder, probably a brisket the week after.
Thanks again
Bruce
