I just purchased 9 slabs of Baby Backs at Costco yesterday for Father's day, which I will put into my smoker. They were $3.69 per pound. They had spare ribs for $2/69, but it worth the extra few dollars for the BB. I have never seen the ribs at Costco with the membrane already removed. I will check and hope they did this chore as it really can be a pain.
Happy Father's Day to all.
