When I was a teenager out tromping around through the woods and brush with a 3030 and never saw anything but tails running away, I noticed most of my encounters were happening on edges. If a deer jumped 50 ft from me, I could run as fast as I could but it would always be gone by the time I got to where I could see it. I guess they figured this out long before I came along. This is the reason for my answer. If they lay on an edge of a field or woodline they can disappear either direction quickly. Theyve got you beat no matter which direction you come from.
