For the pork shoulder rub
1/4 cup dark brown sugar
1/2 cup white sugar

1/3 cup garlic salt
1/3 cup kosher salt

Pork injection
3/4 cup apple juice
1/2 cup water
1/2 cup sugar
1/4 cup salt
2 tablespoons Worcestershire
------------
1 whole pork shoulder (approximately 16 pounds)
1 bottle Big Bob Gibson Championship Red Sauce (or substitute your favorite BBQ sauce)

Inject pork shoulder evenly with injection solution. Apply a generous amount of rub onto meat. Pat so the rub will adhere. Place in a smoker and cook with indirect heat for 16 hours on 225˚F. Serve with sauce on the side or paint shoulder with sauce the last 20 minutes of cooking. When done, the pork should pull off the bones easily. The internal temperature of the pork should reach 195˚F.
