You can't shoot in the dark. Get the extra ZZZ's. Get to the stand when you get there. It's how long you sit that matters. If I don't get to my stand until 8 oh well... most of the folks who go out before dawn are wore out and done by 9 or 10... Just be there when you can be there... Of course who doesn't like watching the woods wake up??? It is nice to be early some days...
