I checked on the venison at 5 pm so 4 1/2 hours and it was 133° internal. I pull it, wrapped in in aluminum foil and kept it warm. I used my wife's ancient mandolin to slice up raw fries and managed not to cut myself. I also did asparagus. When I unwrapped the meat it was perfect medium rare. Not much smoky flavor, the salt level was just right and I could taste a hint of the celery seed on the outer edges, and it was tender.
My shootin' buddy Mick was here and we dined like kings.
