I'm a novice smoker. I have a pretty small smoker. 2 racks, above and below, each 16" round. I've been asked to smoke a brisket and a couple of whole chickens. The chicken is easy. I have done that and will do it on the top rack, no problem. The challenge is the brisket I have is 18" long (10 lbs). Can I cut this in 1/2 or just trim it down a bit then smoke it? I appreciate the advice.
