What is a pignut?  That is exactly what my friend Lee asked when I posted this on facebook!  ha!  I asked Granny and she said that they were really bitter and since we couldn't eat them the farmers fed them to their pigs.  I decided to google it of course - because that's what I do.  haha!  I found a bit more 
info:
The fruit is a peach-shaped nut that is 1 ¼" long. It is thick walled, unridged, and encased in a thin husk that only splits half way open. On the inside of fallen nuts, when split open, resemble the snout of a pig.
The pignut hickory nuts are important in the diets of squirrels, chipmunks, raccoons, black bears, foxes, rabbits, birds, smaller rodents, and whitetail deer.
Interesting.  She did have something about a pig in there!!!  hehe!!
She ran around, got Lucky kisses and took a stroll in the wagon...
