I have never even heard the term before but my friend at Envirocapitatist is one. After you read his site you will understand and be one too! He is blogging out of Tennessee, somewhere near Mushy I think.
His blog is filled with great personal stories about his hunts, his true excitement and joy of just being in the woods and enjoying nature, his family ties, and a sprinkling of personal photos that are really good. It is a great read and with his writing, you can see it all in your minds eye. He needs to get the Old Deerslayer to come visit him. You go see him too.
