What do you do?
Two examples..
1) I'll select 3-6 shooting lanes, depending how trails are and available sign. Then clear my shooting lanes out completely straight, looking at my tragectory of my arrow path too 30 plus yards, usually about 2 feet wide all the way. This way if a deer meanders through the woods, like deer do, I can wack them as far out as I dare to shoot because they must cross this lane at some point. Also, if the deer doesn't "stop" in the exact spot I have a little flexibility being at least 2' wide. I usually will attempt to have all my stand areas cut 4-8 weeks before the season starts, so the deer can adjust.

2) My buddy will only trim a few branches and select his shots based on this, as he claims - which is viable. He doesn't want to change his terrain and spook the deer.
