I usually get in stand about 45min to an hour before 1st light and leave about 10:30 and in the afternoon usually around 3-3:30 and stay until after dark!!! Sometimes I'll stay all day!!!
Pretty much the same. An hour before sunrise puts me in the stand about 30 minutes before first light. And I try to be in the stand for evening hunts no later than 3pm.
My usual time to leave in the morning is 10am, but I will stay longer when the conditions are right, such as cloudy, cold days with little or no wind.
For evening hunts, I never stay beyond the time when I cannot see safely with the naked eye. In other words, i don't use my scope to make out any details that I would not be able to see with a scope in normal light. Not only do I consider this unsafe, but feel it increases the chance of making harvest mistakes. This might include missing a brow tine on a spike, or mistaking a nubbing buck as a doe.
