King, I am not familiar with YOUR hogs out there...but look at all the 'dinosaur' characteristics in that bone! Man he is absolutely scary looking..I bet he was formidable looking in the flesh, wasn't he?
I would bet he was way over 10...maybe 15?
I want to ask you something I've asked lots of folks about here....and never gotten a satisfactory answer.
We have conservatively speaking a thousand plus hogs on our land at any one time...we also have lots of bobcats, coyotes, and gators preying on them. We roam all over the property, thick open you name it..we've walked it.
We have found perhaps a dozen hog skulls in places other than our gutpile over the years. Where are all the hogs going that die of old age on our land? It's a puzzle to me...we find deer all the time...but hogs are a rarity. Are they kind of like elephants? Go to some central, out of the way place to pass? Maybe thats not the case for you as your cover looks very open all over.
