I used to hunt 3,000 acres that was pretty well trod (as is most unposted land hereabouts). We used to call one area "Omaha Beach" because it seemed to draw a lot of hunters who got to a stream and fanned out rather than cross it. It got so I began to focus more on the hunters than the deer . . . and started to hunt the deer escape and cover routes. The trick is to get in early and get to where the mob won't be.
Unfortunately, that usually means a long walk through rough stuff.
I hunt my own land now (thank God) and even so there is a lot of bowhunting and "slug sighting" in the area. From my stand I can't see any further than 30 yards for about 270° out of the 360°. I see fewer deer, but when I see 'em they're walking and close. Even during gun season I've got so I stick to cover and play the human routes as well as the deer paths. Let your neighbors put on an unscheduled & unannounced deer drive for you.
