My farmland is in ND. It's rolling prairie and grain fields interrupted by shelterbelts and empty farmyards. My longest shot at a deer (it was successful) was 265 yards according to my Leica laser rangefinder. My closest could have been measured in feet, because it was less than 10 yards. I've not seen many deer bedded in 4" high stubble. They often feed on grain spilled by harvesting equipment at sundown, though.
