What Cowboy junkie said!!
You only have one oportunity to take qview of your very first wsm smoke and this is it!
My #1 tip is
don't peek, and don't let anyone else near your smoker who might peek either. I have a sis in law who just has to peek. I have a super soaker near the smoker to keep her off. Peeking will delay your smoke by almost a 1/2 hour every time you do it.
Organize your lid opening times carefully. Don't saunter into the house with the plate of meat then realize you cant find the foil or the wife is in the kitchen and you have to work around her. Have a work table set up next to the smoker with
everything on it that you will need. Have the foil already cut to size and ready to go the minute the meat is ready for it. Do it quickly and get it back in there.
I Have an oven thermometer placed on each rack to double check that what the probe is telling me is correct. I check each one quickly then slam the lid shut. I never trust just one probe to tell me what the smoker temp is. Oven thermometers cost about $5 and are the best insurance you can have. I position the top rack thermometer right under the top vent leaned over so that it can easily be read thru the vent opening. Careful not to lean in too close or you will get smoke in your eyes.
If you have a large afghan dog visiting make sure he doesn't grab a piece of chicken and knock over your table in the process. ( Don't ask ) I now have a really sturdy work table and a dog kennel for visiting hounds.
It is really easy to forget to spritz the ribs or add moisture during the foiling process, I have done that more times than I care to admit.
I now have a list of stuff to do and in what order they shoud be done. Its stuck on a pole right beside my smokers so I don't forget stuff. Its saved my bacon on more than one occasion.
Remember to have fun. Part of that fun is taking some qview for us here at SMFto drool over.
