well, for anyone with the same question in the future. the answer for me is...
2 racks, wrapped and held in a cooler, unvented, works out just fine.
32 racks...i'm surprised the fire dept. didn't show up due to the cloud of steam that came out of the thing when we opened it.
holy fall off the bone! but, oddly enough, the meat wasn't mushy.
i would NOT do it again.
follow the advice of the others above, i just couldn't make the time to grill/reheat. in the future, i will just have to find it.
