Keith W., You can wrap it in heavy duty foil and a couple of large towels and stick it in a decent cooler for up to five hours. Maybe longer if you warm up the cooler first. Fill it with very hot water and let it warm up until you're ready to put the butts in.Don't worry, they will still be very hot when you get ready to pull them.Spring "Somebody Has To Be Up At 3:20 AM" Chicken Spring Texas USA
