It's been my experience in the past that when the rut starts tapering off you'll still see the bucks cruising the countryside looking for the last hot does, but what you won't see as much is bucks actually running the does. The activity tends to taper off over about a week's time, then pick back up a bit that first week in December. A doe decoy and/or some doe in heat scent are usually pretty good tactics for luring in those bucks who are still on the prowl.
