When I did mine for the wedding this last weekend I smoked them unwrapped for 10 hours wrapped and put back in the smoker for 2 more hours then just tossed them in a preheated ice chest until just before service when I shredded them. The juice in the bottom of the ice chest was incredible! There was just about 2 1/2 to 3 cups. What was more amazing is how hot the butts were after 6 hours in the ice chest! I tempted them at 152 degrees whole! Just tossed in some finishing sauce, placed 2 pairs of tongs in the chest and watched it disapear!
