RC, maybe that's why they call 'em pignuts?
I can remember hearing the hogs going through the woods eating them. You could hear the crunching sounds before you saw them.
An off-subject comment: Dean Torges has an interesting entry on his blog at thebowyersedge.com on hickory nuts, for human consumption. When I was a kid, we harvested (not killed
) them and hammered them open for the sweet meat inside. We only used the "scaleybarks", or shagbark hickory. My aunt cooked with them. We harvested them by the buckets-full in a good year.
Does anyone know which species the deer are eating? There are several "pignut" varieties. George mentioned bitternuts. I have several species on my place, and after reading this, I may have to move a stand or two!
