This is labor intensive but worth it.
1 pork roast seasoned with your choice of spices
1 1/2 cup cola
1 bottle bbq sauce
Cut all visible fat from roast,put in crock and cook 12 hrs (i put mine in before bed and let cook all night) on low.
Remove meat from crock and drain all juice from crock.
Shred meat and return to crock add 1 bottle bbq sauce and cook 5-6 hrs more.
MAKES ALOT!!! Freezes great.
