Jslotter pretty well covered it. The only point that I would again stress is....
YOU HAVE TO KNOW YOUR GROUND AS WELL IF NOT BETTER THAN THE DEER DO!
Yes, you can wander into a woods for the first time and if your stillhunting skills and techniques are soild you may very well get close enough to make a kill. But believe me, you are stacking the already low odds that you will get close enough for a shot even lower. Then there's also the fact that when you KNOW your woods, you also know of where in that woods you go to begin stillhunting on a given day based on your previous knowledge. Having an intimate knowledge of your woods is KEY to you finding where the deer are, and also to you seeing them before they see you. By this I mean of course the terrain and cover and how the deer use it, PLUS a working knowledge of the wind patterns, thermals, low areas that act as scent "sinks", and how the terrain affects the wind when it's gusting. In my scouting missions during the pre and post seasons, I carry colored smoke bombs for this very reason. I've amazed at what these things have taught me about the wind and thermals on ground that I thought I knew "like the back of my hand"!
Two final points.....
1. Be advised, this is NOT an easy way to hunt. Don't get me wrong, I see and get close to just as many deer as when I stand hunted, but the big difference is getting a SHOT. That's tough. Granted, I am extremely selective with my shots, and being on the ground with no shooting lanes reduces the shot opportunities even further. But the challenge and satisfaction I get from getting that close undetected and once in a while a good clean kill is like nothing else I've ever experienced in 43 years of deer hunting. It's such a rush that I don't want to hunt any other way now.
2. I would strongly advise anyone who wants to try hunting this way to get a copy of G.Fred Asbell's "Stalking And Stillhunting, The Ground Hunter's Bible".......
