RE: Best time to hunt?
In Pennsylvania, it would be the first two days of the rifle season - followed closely by the two Saturdays.
If you are in a area that is posted and do not have the option of other hunters to move the deer for you, my answer would be from first light until 1 and then 3 pm to dark.
First thing in the morning and the last hours of night at the time when the deer are most active.
