I have two shoulders i have been smoking today. My question is, how important is it to let them rest in a cooler? I have the smaller of the two wrapped in foil and a towel resting in the cooler now. And the second shoulder is still on the smoker at about 190* heading for 205* I have to be to work at 4 in the morning and don't want to rush anything. But I also don't want to ruin two great looking roasts after an all day smoke.
