Be happy you don't have the disability issues that I have. I can't even sit with my back against a tree for more than a few minutes at a time. My back brace is way too uncomfortable for that. And if I sat on the ground these days, I probably wouldn't be able to get up without some help. And I'm not even 60.
Btw, as a fairly poor young man, I couldn't afford to buy a stand and they disallowed putting nails in trees, so I often hunted from my knees with my recurve, that I drew, held and fired just fine. I'm really not sure what the argument is about the ground thing is.
Btw, not mad at you, I mentioned several times that you're entitled to keep your state any way you like it. Look forward to hunting wherever, whenever!
