Hi. I'm looking for a place near Detroit to purchase organ meats. Specifically red meat, beef hearts/liver/kidneys etc. Also bison/buffalo/boar. So far I have only found beef liver. I'm looking for grass-fed if possible, but I understand that may be near impossible to find so I'm willing to settle with conventional. If anyone knows where to look or any butcher shops that carry exotic or organ meats [[especially beef heart + kidneys) please let me know!
