Im not sure on a good set up but i was reading a book by fred asbell called Stalking and Still hunting. It had a section on ground blinds and one thing i can remember is that you can dig a pit so you are down lower and you dont have to build the blind around so height. Also he said make it look as natural as possible. For example if you are hunting a river bottom and it floods and tree trunks collect old branches and kinda make a wall. And than u can just add on to that.

If you are interested in stalking and still hunting get this book it will help you out a ton. It covers everything. Good luck and have fun
