Those Tasty Animals

I had bear roast once many years ago. Not bad at all, quite tasty matter of fact. This is a question for all who hunt and eat their kills. Do you usually add fat to the meat, since game meat is usually so lean? Friends who hunt end up adding pork fat to their ground mixes so it won't be dry. Is that right/wrong or what do you do? And if this is hijacking, I apologize.
