pork butt

Knowing that the snow was coming, and I already had two bone in pork butt's in the fridge to be smoked, I moved the Weber 22.5 smoker into the garage so that it wouldn't get buried under 10" of snow. After the snow had passed, and the driveway was cleared, I moved the smoker into a spot normally...

Hey everyone, I'm doing my third attempt at pork-butt; first two came out awesome but this time I'm trying an overnight cook. I planned on doing the minion method and checking up on it, but not like my usual evey 45 minutes or so when smoking. Any tips on the overnighter? Thanks
