I have found this to be 100% correct. Field fed Midwest deer taste almost like grass fed beef because they are eating almost the same thing. The mulies I have gotten have been around sage brush and definitely came thru in the meat.Depends on what they have been eating. A mountain whitetail tastes a lot different than a field fed deer. The same is true about mule deer except mulies tend to end up eating sage brush and that definitely makes their meat taste quiet strong.
