Nice pics, bud. You need to teach that little one how to pinpoint. That hole looks big enough to bury someone in.
If you have permission for that field in the background of the pics, I would hit it. You live in a very historical country, my friend. There are coppas all over that field!
Welcome garryson,
Sounds like a great day spent with family outdoors! It doesn't get any better... I can tell by the smiles. Good luck to you and keep posting your finds for us. Take care!
