Good for you. You're never to old or to young to start hunting. Once you get it in your blood, you'll soon learn that hunting is more than killing and the joys of learning and experiencing all things out of doors is worth more than any one and all video games can ever give you. Here's a link, go down to your state and you'll find the contact info. for your state's wildlife resource. You need to contact them and get yourself enrolled in a hunter safety class before doing any hunting. The hunting safety class will not only teach you proper hunting ethics and safetybut will get you started in the right direction. It might even get youin contact with an adult leader that could get you out away from your back yard for more hunting opportunitys, as there are often youth hunting opps. that you otherwisewould not know about.

Good luck and I hope you learn to enjoy the out-of-doors and hunting.
