So,
Unfortunately the area the birds are in now may not be where they are in the spring. Generally, birds will break up before the spring and only good scouting will ensure your take of a big gobbler. Don't expect to have to use corn or fancy deeks... Get a few calls NOW and get used to them. try and mimick hens as well as possible. The NWTF website used to have wave sound bites of turkeys you could listen to and the diferent calls they make.
If your going to hunt this spring, getting ready starts now and not opening day, if you go out with doubtful calls and a fall location area... your chances suck.
Get a hen decoy, don't bother with a jake, you don't know how the birds will react to it.... Hens are just to get the attention off you anyways, put it 15 yards directly in front of you. Post up an area that you can see well... make sure you've got some good cover. Put the sun at your back, nothings worse than having the sun in your face.
Pattern your gun... I shoot differently than you do, what I do probably won't work. Get your gun, buy a turkey tube and get about 5 boxes of shells, get a turkey target and pattern your gun at 35 yards. you want to get at least 7 pellets in the head of the target to consider a kill.
