RE: Trim off the fat?
When it comes to deer meat, if its white, cut if the heck off!! You can allow a little bit (I don't allow much though) of the white stuff if your grinding the meat into hambuger. If its steaks or sliceing the meat into jerky, cut the white stuff off. Its tough to chew, its not tastey, it takes away from the flavor of the vension. I only have experience with whitetails. Other big game animals may be different.
