The marinade recipe was originally shared with his father's co-workers, all of whom had been avid hunters. He began selling the marinade as "R.C. Parks Authentic Jerky Juice", and had distributed it through sporting retailers like Dick’s Sporting Goods and Cabela’s.
His son Matthew eventually took over the business. Now as "Jerky Gold Marinade", Parkes offers his father's famous recipe to hunters and anyone else wants to make their own jerky at home.
