Re: ...two miles of cables that miraculously remained untangled.
You say that, but I'm eternally in awe of anyone who can pack two miles of cable and somehow not have them immediately tied into physically impossible 5-dimensional knots the moment they turn their back.
Well, the secret is that they don't have RJ45 connectors each end, so their propensity to tangle (with themselves, and all the others) is greatly reduced.
