I suppose if one takes a stance, he should explain that stance from a logical POV. Since I have become a ground hunter and am definitely in the minority among bowhunters and trad bowhunters especially, so I'll try to explain my choice.
First, the advantages of tree stand hunting are many; you're out of the straight line of sight from deer on the ground, your scent stream takes longer to reach the ground and has more chance of being dispersed before it reaches the ground, you can see further and have a more complete field of view the higher you go. Having stand hunted for many years, this is undeniable.
However, having narrowly escaped serious injury while removing a ladder stand 10 years ago, I began to re-think my position. Fortunately I was left on crutches for 3 or so weeks with nothing more than a serious sprain after a fifteen foot drop, but it could have been much worse. Had the ground been frozen, the ER Dr. told me my ankle most likely would have been broken. Figuring I had used up my 'Get Out Of Jail Free' card, I changed it up the following year and have been a ground-pounder ever since. Here are some of the positives of natural ground blind hunting, from my perspective:
1) Easy in/out
When hunting public land, as I do, the rules are pretty specific WRT putting up tree stands. No nails, screw in steps or hooks/hangers are allowed. Stands may not be left up overnight in many PHL locations, which means carrying in your stand and climbing sticks, and taking them with you when you leave. ATVs are also not allowed in many locations...do the math. My portable stool weighs less than a pound, can be slung over my shoulder with the attached sling, and walked in with my bow and day pack to a predetermined blind site (usually a blowdown or large tree I've arranged a brush-out around). One trip, then sit and hunt.
2) Line of sight
While it's true that you can see much further from an elevated stand, it's also true that if you can't see deer at that distance from the ground, they probably can't see you either, if you are still. Since I limit my shots to 25 yards or under, I really don't need to see a deer 100 yards away other than to try to coax it in closer by calling or rattling. In a ground blind, your ears are your friend, many times tipping off 'incoming' long before your eyes do.
3) Scent
While true that as mentioned above, your scent stream behaves differently elevated than from the ground, I find that using scent control methods can generally keep your scent down to a minimum. When hunting from a blind you really aren't as concerned about watching your downwind area, because deer are likely going to scent you long before you see them. If you position your blind downwind from your shooting lane, you can still get plenty of field of view where the deer will be upwind of you, giving you the advantage.
4) Flexibility
If the wind shifts, you have the easy option of picking up your stool and moving 100 yards at a moment's notice.
5) Terra Firma
Even in the best of tree stands I feel ultra-cautious. The safety harness I wear is restraining, uncomfortable, and doesn't give me any confidence to lean into it for difficult shots. I always feel like I'm walking on eggshells regardless of the stand, though ladder stands are much better. You don't have to worry about falling asleep, slipping on the way up or down, falling out of the stand onto a sharp broadhead (or worse) or crippling accidents. If you fall asleep on the ground, you might fall off your stool, but that's about the worst of it.
6) Comfort
Generally the winds are calmer at ground level, no seasick-swaying nosebleed carnival rides on the ground. You can stretch your legs and move around. I suffer from a bad back and sciatica, and sitting the ground gives me the flexibility to shift and move when I have to, and not get busted from 100 yards away. You can set your pack and other gear where it suits you in your blind and not worry about things falling or being accidentally kicked or blown down.
7) Longer time in the saddle
Rather than spending time setting up and taking down stands and ladders before and after (and getting sweaty in the process, you simply walk in, park your posterior in the saddle, and begin your hunt. Easy peasy. Tired? Go ahead and snooze a little. Bored? Read in comfort...no worries.
8) Security
In those PHL areas that DO allow overnight stand/ladder installations, you don't have to worry about locking or securing your gear...because you walk in/out with it. It's not there to steal.
9) Shot angle
No more worrying about downward angling shots and trying to calculate entrance/exit angles...if you get the shot, take it.
10) In Tune
I've found myself to be much more in tune with nature and my surroundings on the ground, rather than being detached and isolated in a tree. I get to see squirrels, chipmunks, rabbits and other small game up close and personal. And I've been eyeball-to-eyeball with a surprising number of deer from my blind, the past season with a small (too small to shoot) doe grazing not 15 feet away, apparently undetected, until the wind shifted after several minutes. It was truly an enjoyable experience and I left that day feeling all the better for it.
Obviously, ground hunting is not for everyone, but I've managed to make it work for me. If anyone has been considering giving it a try, I would encourage you to have a go at it and see if you can make it work for you as well.
