I don't believe heading in any earlier is going to help your hunt at this point, If you're bumping him on the way in now
you could make it a lot worse if you go in while it's too dark.
If he hasn't been bumped out of there yet that tells me he isn't going anywhere, he's a crafty Buck and isn't about to
let you push him out of his home otherwise he'd be gone by now.
So I suggest heading in about 30 minutes before sunrise, that should be a good time to get you and your son settled
into the blind BUT I can't emphasis enough how important it is to be quiet, still and Descented. he'll get brave and show up I bet.
Democracy is two wolves and a lamb voting on what to have for lunch.
Liberty is a well-armed lamb contesting the outcome of the vote.
