I think Whiffletree farm usually offers beef bones, and they have neighborhood drop off points. 4P, which has home delivery, sometimes does as well. Less sure about offal, but you can check any local farm that offers cow or pig halves or parts to consumers.

Soko Butcher just opened in Takoma Park. He focuses on farm-raised meats. I've seen chicken feet and beef bones (marrow and knuckle) there.

Just moved here a few months ago, and wondering if anyone has any recommendations on where I can find good quality, pasture raised, organically fed beef bones? Also livers, chicken feet. The only place I’ve found to buy bones at all have been the Asian grocery stores, but their meat typically isn’t the quality I’m looking for.

Thank you!
