Go to Walmart for royal oak. They have like 8lb bags. It's great stuff. I always use it or Stubbs natural briqs for my longer smokes....
Be sure to break up any huge lumps and pick out any bricks or insulation.
One bag should be plenty!
Anxious to hear what you think of it. Be sure to post your cook!
