RE: Walking quietly
Try a leaf blower. I know a first thought thats crazy, but if most of the leave's have already fallen you can go in one afternoon when deer are bedded up. Blow you a path that is large enough for an ATV to go thru, that way if any wind comes thru chances are it will not fill the main walking area up. I do this every year and its one of the best things I could do to help my hunting season. If you don't have a blower, borrow one or rent one for $30 a day. Best investment you'll make.
