What no pork rinds or cracklings? My mother used to make cracklings. I bet if a doctor saw us eating them today they would have a fit with us eating all that fried crisp fat! Mom used to salt them down and let them cool a little then we'd make them disappear.
When we used to butcher hogs in the fall there was an old couple that lived close to us. They would always come over and collect the heads (sometimes we'd butcher four to eight hogs at a time). And they'd make head cheese out of them.
