The turkeys in my area have a certain radius they travel throughout the year. In the winter they are flocked up pretty good. So at that time their routes differ from what they are when the flocks break up just before spring. Some do tend to stick to the same areas they ran in the winter but when the warmer weather kicks in the available food sources increases for them and they will adjust their routes to where the food is. That is what you need to look for. Water sources, food sources, etc... Find where they are roosting now, then keep a record of where they go after fly down. As the weather changes watch for what directions they are moving in end scout those areas. Scouting on a regular basis is going to be the only way you find where they will be once Spring hits. Once you have an idea of how the birds in your hunting area travel you will have a good idea of where to be come opening day. Be careful not to disturb there patterns though. Keep a good distance from them and try not to spook them. Since the area you said had little hunting pressure they should probably stick to a pretty rutine pattern through the day. A good pair of feild glasses would do you good. Remember DO NOT use your calls before season starts! You can use locator calls sparingly but you do not want to educate them to the calls you will be using come Spring.
Well! Hope that gives you a good place to start from. I'm sure you will get some good info from the others guys here that will serve you well. Good Luck!
If it gobbles,runs on gas, or is married to you it will give you trouble!
