I cannot fathom that in many of the places I hunt either in the big woods/reclaimed strip mines south of me or locally where everything is cutout regrowth. They can and do bed any where around my spots.... Sure I can narrow it down but no where near 100%... I would put mine at 70%.
I don't hunt to much big woods Buckeye.. mainly swamplands.. smaller woodlots (under 100 acres).. etc etc etc. In Illinois.. big woods are scarce and not the norm. Even the public land I hunt has inadequate woods.. you really have to travel to see any bigger woods (above 500 acres.. even above 300 is pretty scarce in the entire northern half of the state.)
And southern Wisconsin (although better) also has little acreage that I would ever call big woods.
