Just got an s.o.s. call from my son. He and his in-laws have planned a party for this Saturday and the main course was SUPPOSE to be a 100 lb roasted on site pig, well the pig guy/cook backed out. So I offered to do some butts in my smoker, a master forge dual door propane. I think I can get 3 butts in it ,my question is how long can they stay foiled, towel wrapped in a cooler safely. I plan on cooking them at my place then taken them to the party when we go and pulling there.
