I've shot almost all my bucks in October.
Where I hunt, the food sources change the most during this month.
The deer are eating the last of the greens and wild grapes before chowing down the white oak acorns at the end of this month..don't get me wrong, they are eating acorns, but I will see many more bucks at the dwindling summer food sources than in an oak grove in October.
If I can find the last of the wild grapes here each year....oh man. I will see bucks up to 10 a.m.
Not in the quantities other places have, but if I wait, I usually have a shot at a nice buck or two in October this way.
