Does anyone have black walnuts?

I am looking for black walnuts on the ground or recently picked to start some new trees. Does anyone know of some black walnuts for the taking?

Not a personal endorsement; I just happened to remember having seen these:

the PDF for when that’s deleted, so we can know what it was.

Wear gloves when you collect them: the husks will stain pretty badly.
