Chuck is about my favorite thing to cook, and i've done a lot of it for other people, and its always a big hit. Its also about the easiest thing there is to do on the WSM. Rub it, throw it on until you like the bark formation, slap it in a pan, pull it when its tender, no need to ever temp it, it'll tell you when its done. I use a foil pan with onions on the bottom, keeps the roast out of the grease and also adds nice flavor. If you have a Sam's by u, there chuck is great, big 'ol hunks of it!
