Howdy! I'm a civil engineer who grew up in the Phoenix Arizona metro area. My wife has family in NW Arkansas, which is where my introduction to Q started. They have HUGE tank smokers, and know how to use them. I was taught pit smoking from an old farmer. We cooked for our church, burying a cask in the ground with 400# of meat.... amazing! Now I've used an offset smoker for the past 5 years. Made a huge block smoker for my church for our pig roasts and mens events (500-lbs of tri-tip, roasts, and shoulders). I'm making a smoker now for my sons high school... and need help. I'm starting here.... I intend to show a "design", and look forward to getting corrected along the way..... Best wishes, and thanks!!!! Bubba Berr.
