Wow! Nice looking brisket.
Fortunately we have a Costco within a few miles that carries prim brisket full packers for just pennies more then Sam's choice cut I think they are around $2.79 a pound right now. It's all I buy and the good news is that they are building a Costco right down the street from me. I don't like their pork butts because they debone them so I buy those at Ssm's which is just a few blocks from my house. I am vey fortunate to have both clubs so close and have a membership to both. But
the way I smoke my briskets you really can't tell prime from choice, they all come out tender, juice and tasty from flat to point every time.
