Tom,
I haven't ventured into the Bow hunting world. Yet. Perhaps because my wife, who is right, thinks another gear intensive hobby is out of the question.
As for hunting, deer I assume, the key will be practice. Most of my buddies bow hunt (I'm a fanatical bird hunter). They are always, always nocking up in someones backyard. Military training will help here - think swift, silent deadly!
Good luck Fred Bear!
