I am also an avid deer hunter and in my opinion, reading and hunting are awful bed-fellows.
I missed chances or gave away my position numerous times to deer while reading and finally convinced myself it is a bad idea.
I then got smart and got an IPOD and loaded books to it – and used a set of ear buds with one bud cut off and just listened in one ear.
This is a great way to pass the time but is not a great way to deer hunt, as you are deaf in one ear and are also distracted by the story.
As far as helping me stay in the stand longer, many of my days are re-planned - 6 am to 6 pm, so leaving is not an option.
In 2016, I let a great 140+ class ten point walk right under my stand and I did not see him til he was at my 11 o-clock walking straight away and he offered no shot opportunity. I did a light grunt at about 25 yards, hoping he would stop and turn and present a shot, but that was not the case. Last I saw him, he was still walking, dead away…. I am not 100% positive but I believe it was about 1330 when this happened.
It is possible that had I heard him, I might have been able to change the situation – but I did not hear him and as you already know, was not able to turn him.
So, no books or IPOD for me in the stand, even midday.
If you simply must read something, my recommendation is the Gunslinger / Dark Tower series by Steven King. Best set of stories I ever read but man, are they long.
Louis L'amour, Ralph Compton, Pat McManus are some of the ones I've enjoyed in the woods over the years. I once spent 8 hours in an enclosed tower stand in the pouring rain with a Microsoft book. Can't say as I'd recommend that one though.
