Gonna go to the Pechanga BBQ Comp in the morning and check in with my friends Smokin Harts, then (get ta Smokin) Maybe around 2:00!!!!
Are you prepping the shoulder for the comp? If so it won't past inspection. If you are bringing it to hang out and throw down, I would rub and wrap in the morning. IMO anything past 3-4 hrs starts to turn the rub to mush and wants to fall off and not bark up
