I also considered lighting a few coals in my regular cheapo grill on one side and putting the tube smoker on the other and doing it that way, with the temp a bit higher to help avoid any bacterial growth with some heat, but not enough to really get things cooking. I suppose I could do the same thing in the PBC, Have a few lit coals on one side to bring the temp up enough to stall growth. If it's an 85° day you may as well hotter, seems the only option.
