I don't know about anyone else but for me it is partly the tradition and partly because it seems cool as can be! Ever since I read "My Side of the Mountain" I have always wanted to be a falconer.
My first experience with a falconer was about a year ago. He has been a falconer for 30 some years and has a GyrSaker falcon. He also makes some of the best hoods I have seen! I though it was the most interesting thing when I walked into his living room and there sits this magnificent falcon!
