It has been my experience that turkeys seem to hang around in the same areas year after year, during the same season, unless there's some drastic change to the habitat or unless there's too much activity there.
A few years ago a tornado went through one of my best hunting areas on some public land in Southern Illinois, knocking down hundreds of pine trees. That certainly caused a change! Other than something like that, I've seen turkeys in the same areas year after year, again in the same seasons.
I would however not put too much into winter scouting when it comes to where you'll find the spring birds.
Birds tend to group in very large flocks during the winter. Here it's not uncommon to see a hundred or even more in January or February. When spring comes, those flocks break up and scatter. I've watched winter flocks who stay in pretty much the same area and then go back to that area in the spring and not see a bird there.
I also think that you can "bump" birds from a roosting area with too much traffic. If, in the spring, you find a roost tree, especially just before the season, I personally would stay out of that area until the season arrives.
I certainly like to know the general area where turkey are in the spring but I don't do a lot of pre-season scouting of that exact area. I think that the turkeys are much more likely to see me that I am to see them and that may just cause them to move to another less active area for a while.
