RE: When is the best time to hunt where??
As a general response...hunt deep in the woods in the morning if you can get their without making much noise or going through the field. Generally deer are leaving the fields in the morning to return to the deep woods to bed down for the afternoon.
As for you stands along the fields, hunt them in the evenings when the deer are coming out just before dark to feed in the fields. You'll probaly see mostly does in this field, until right before dark when the bucks will start making their way into the field.
I hope that helps some.
