It doesn't take a rocket scientist to disrupt one of these systems either. Just let the single strand run into a conduit that travels attached to an overpass on the highway. Now let an over tall truck hit the underside of said overpass. Took 4 men about 30 hours to unscrew that mess. I remeber, I was one of the four.
