RE: Minn question
From my experience hunting in Minnesota, you would be wasting your money using doe in estrus in October. The rut will just be getting under way the last week October and will be at its peak in the first two weeks of November. I would recommend using a grunt call with rattling horns and a buck decoy if you have one. The bucks will be starting to start patrolling the fields for does and will be getting protective of their territory.
