Pulled pork for large group

The Costco and Sam's Club pork shoulders are sold in 15 - 16 pound packs, 2 shoulders or butts about equal size. 3 or 4 large crock pots will get it done. In each crock pot, put a can of coke, minced garlic and onion powder. The butts will take about an hour per pound on high. When they are ready to pull, drain off juices (save some for au jus), then pull and add back to the crock pot with just enough of your favorite bbq sauce to make it wet. DON'T over sauce or no one can taste the meat.
