I saw a special on Hormel Black in the special stack packs once. With a sale price plus one of those coupons, it was about $3 for a 24 package. I got a bunch of them and froze most. It was really good and I believe available nationally. I don't think that was something that they would produce regionally (like dairy would be). I tried the versions smoked with pecan wood and with cherry wood. They made a big deal over those types of woods being used in meat smoking competitions.
