Because I hunt mostly from ladder stands I go in 30-40 minutes before daylight. No matter how careful you are jumping deer is always an issue that we can't predict nor fool them in their own back yard. They will be back and most times just wait you out and return to their normal activities. I leave when I can't see anymore and try to time it when I'm not seeing or hearing any woods movement. I'm also in the upper 50's and like ladder stands for safety reasons. I have a new climber but just haven't got the nerve to use it yet. It's going down to S. Ohio so we'll see maybe I'll try it. I use a modest fanny pack to pack all my gear into.
