Like Joe said, if your birds flock up for winter, don't bother looking for them until they break up and spread out in spring.
However, for me, scouting turkeys is as much about getting to know the land you hunt as it is looking for birds. Right now, while the leaves are down would be a good time to find out where the gullys, fencelines, open ridges, travel lanes, etc. are. You can do it now and not worry about spooking birds. Then next spring you aren't bumping them trying to do the same thing.
