Not sure how the deer Doctor makes that prediction. So many factors goes into it. Sounds nice but if it turns on to 85 degrees you are not going to see much rut activity. Was in Missouri last year and it was warm. Had a mosquito bite me on November 4th near Iowa. Small bucks moving only until a week later. Its great to be in the woods in November in the Midwest but its got to be fore the experience and not for the large trophy.
