Everything that goes into a cow is plant-based. Hay, grain, grass etc. all plant-based. So sink your teeth into a good quality piece of Montana beef and do your testbeds and your own state's economy a favor.
Cooper, was born Frank James Cooper in Helena back in May of 1901. His parents came from England and had settled here in Montana. His father bought a ranch and Cooper would spend his summers on the ranch doing "cowboy" stuff, which would no doubt come in handy when we would later start in some major Westerns.
