Place roast in crock pot, add one can of coke, diet coke, or beer.
Sprinkle roast with garlic powder or make several small slits in roast and add cloves of garlic.
Set on low and cook for about 9 hours. When the roast is finished cooking, remove from crock pot, cool enough to shred. Add sauce and heat or serve sauce on side. Serve on sandwich buns with sliced pickles, raw veggies, slaw and/or chips.
