Look what I found at the grocery store
I was just going to grab a brisket and go, but after picking out a nice looking 11 lb slab of beef I notice whole pork loins on sale for $1.79/lb.  Less than the brisket in my hand.  So I say aloha to the brisket and say aloha to a pork loin.  Just under 12 lb, and a nice 3 lb chuck roast just for fun.  Seasoned with the rub and, since they're both nice hunks of meat I started them at a higher temp (450°) and just let the fire run out.  Into the cooker at 1:00 p.m., the beef was done by 2:45 and I left the pork on until the fire burned out by 4:30 p.m.  Wrapped the loin in plastic and foil to cool and refrigerate overnight before carving.  Delicious.  I think I'd walk past a pork butt for it.  The shoulder cut was tough.  Next time a two inch sirloin instead.  I only burned six sticks of seasoned oak for the cook. Twelve pounds of pork loin because it was there.
