Climb ladder. Throw heavy blanket over razor wire. Maybe throw second one if you are really cautious. Climb over. The effectiveness of walls and fences can be easily measured by going to a prison. They have at most a mile or so of fence line, and no shortage of material to work with. Yet they rely on guards as the only real way to keep the inmates in. Fences are to slow them down for the guards, not to keep them in. So any wall/fence idea that doesn't include a guard tower every quarter mile or so, ie about eight thousand towers, is pointless.
