Nice piece, as others have mentioned I don't see any way that isn't an arrowhead.
I've hunted north of Orange County and south of Orange County a bunch of times, and I don't think that material is local. Your papaw might have picked it up on vacation if he ever went to the Carolinas or somewhere else where quartz is more common. In your area you'll see a lot more grey/blue hornstone and maybe a mix of beige & greenish beige materials from north and west of you. Your local material is Paoli, beige & pink, but it's not super common in your area. (The same chert is found in Kentucky and it's a better quality, the stuff that is exposed in Orange County tends to be chalky with more cracks from what I have seen.)
Absolutely, old farmers having breakfast or coffee is a great way to get access especially if you and your family are local.
