If you can get to some high ground to glass at first or last light, you might be able to locate some roosting trees in the vicinity of clearing or farm fields. Other options include using locator calls such as coyote howls, crow call, etc. and expending boot leather looking for turkey sign like tracks, j-shaped big bird turds, or feathers. Bring your binocs, some snacks, and enjoy being out in God's awesome countryside.

If all that fails, simply ask the landowner where they are, most likely they can cut down on your scouting time.
