I hunt escape routes exclusively on one of my local WMAs. They are not always easy to find. In fact, some of them I found purely by chance. I look for bottlenecks with cover leading to areas other hunters avoid. Luckily, Oak Ridge only allows scouting on specific days, so I can actually sit and watch what deer do when hunters enter the area. I get in as early as I can, and stay as long as I can. I hunted a new escape route last year...I actually watched another hunter moving around about 500 yes away. He was across a grown up powerline and the easiest path from him to me was a narrow point of a ridge that ran out into the powerline. Everything else was very steep. The deer crossed the powerline, skirted the side of the ridge and crossed the gap I was sitting in, 30 yards in front of me. I found this escape route by accident. I was scouting with my daughter and we were moving slowly, looking for sign, when several deer almost ran over us. After they left, I crossed the gap and went o the ridge line where I saw two other people scouting on the other side of the powerline. I killed 2 deer there on the December hunt last year. I think less than 40 were checked out for the whole weekend. I have another stand out there that is in a narrow strip of trees next to a very wide powerline right of way. I am on the edge of a safety zone, and when hunters pile in there in the morning, the deer pile out, right past me headed for the safety zone. I have killed 3 8-pointers there and several does. I had chosen that stand based on aerial photos, knowing everyone would go in past me to the big woods. A third area I hunt out there is a thick finger leading off the arboretum property to the golf course. It is great the first day, but the deer stay on the golf course after the first day. A fourth escape route I hunt out there is really hard to get to, and it is a deep gap on the edge of a safety zone. Deer file up the old logging road running through that gap all day long, escaping everyone that is walking around on the nice roads at the base of the ridge.
Escape routes can be very productive on public land, especially if the pressure is concentrated as it is at Oak ridge. I use terrain and cover to find them. My rule of thumb is......deer will follow the easiest route they can without being exposed to reach the safety of heavy cover. It has worked EVERY year I have been drawn for oak ridge.
