I would read as many of these posts as you can. This is a great forum, but works best if you have some specific questions. I would also watch some hunting videos---but with the knowledge that it is not as easy as the videos make it look. Butthey do give you a "feel" for turkey hunting. Subscribe to a magazine like Turkey and Turkey Hunting. Get a CD of wild turkey calls and do some practicing with a variety of calls. Go turkey hunting with someone who has experience. Finding a turkey hunting mentor is the best advice I can give.
Below is a link that has a lot of good turkey hunting info. But browse through this forum and you will also find a lot of info.
