I have had the LBGE for only a couple weeks and extending my learinings beyond Baby Backs. And by reading the forum I am not the first to try a pork butt for the first time this weekend. At 9:09 I put it on. Rub, some mustard and brown sugar was the recipe. I have it hanging at 230. Plan on monitoring for a while to make sure it hangs in the 220-250 range. I am glad I went out and bought a galvanized vent cap as we are finally getting some summer like weather here in Orlando. I will post as I go, and hopefully not for emergency advice. Happy Memorial Day everyone, be Safe.
