Turkeys are pretty common all over the u.s and to answer your question about terrain they need 3 common thing. Water,fields and timber to roost in. Concealment is a big part of the game as they have incredible eyesight and being proficient with your calls is important. Never over call as all that does is educate them. Peak their interest then stop. As far as guns go, any 12 or 20ga will work as long as you use the proper loads and a full or extra full choke. There is really to much info to try and put on one post but i would recommend getting your hands and some magazimes and books. Also start practing your calling now. Hope this helps man.
