Greetings, hope you enjoyed your chuckle at the topic. Seriously though, I am a complete newbie. Did a pork butt, quite tasty. Did a small slab that I cut in half and both halves fit on one rack. Now I have a larger slab of ribs. Does it make any difference what rack I put each on? Top, bottom, middle? Should I leave a empty slot in between. Thank you in advance for any personal knowledge.
