A guy I work with is a much better hunter than I am. He gets a buck every year (I usually get one about once every 6 years on average), and he told me that during a Full Moon the deer can feed all night, and you won' t see many at dusk or dawn. Best time to hunt is in the afternoon (11 to 1).
On the other hand, on dark nights, THEN the mornings and evenings become productive.
