Hi, this is my first post and this is a big concern for me as I plan my farm. I am probably going to go with a double fence with a 4' barrier between them where I slowly grow a living fence between the two fences. Once the Osage Orange or Willow has established itself as the living fence I plan to add thickets that can be used as forage (blackberries) but also block line of sight and provide a more thorny obstacle to make it near impossible to penetrate the fence and add to the line of sight blocking. This will all take time, which I have now and you probably don't...so this really doesn't help, sorry.
Dealing with humans is tricky due to their intelligence, even if it is wrongly placed. I don't think you can really stop one with out some sort of surveillance and a reaction force. In the Army, we knew obstacles could be breached but they gave us time to observe the enemy and react accordingly.
Maybe live stock guardian dogs? Do they work with deer?
