I got a PM from one of the other guys with a to Dad as well. As he was a veteran of World War II and Korea, I am sure he appreciates it every bit as much as I do, thank you both, it means a great deal to me, he was my hero.
I smoke mine real slow, about 6-8 hours at least, down around 225 degrees F. I do the foil thing for the first 3/4 of the time or maybe more, and then I open the foil, slice the rack in half, and put it in rib racks and baste them with my sauce.
