I'm doing 5 slabs of baby backs for the 4th. I have to make an appearance at the father in laws for about 2 hours. If I smoke the ribs to get done just before I leave for the father in laws, should I keep them wrapped in foil in a coolor or maybe an oven set at it's lowest setting? or should I just smoke them in the morning and chill them. and sauce/reheat in the oven when I get back from my father in laws?
