I agree pav, though I always hunt hard form October 31st I have discovered after the primary rut to be good hunting.
The last 4 out of 6 years I've killed bucks on November 16, 17, 17 and 29th (Kansas). With the lowest scoring being a 146" 8pt. Three were grunted in to my set and the fourth was patrolling around the edge of a cut corn field looking for does, I believe.
In 2014 I killed a 138" 9pt on November 25th. So 5 of my last 6 bucks have been taken in the back half of November. All but one, have been Indiana bucks.
