It was somewhere around Barstow, on the edge of the desert, when the
drugs began to take hold. I remember "Dave Plowman (News)"
saying something like:

Only a fool would run cables diagonally across a wall.

I've seen it done several times, from the cooker switch to the final
emerging point of the cooker cable to the cooker.

Feckin' potentially lethal, and that was done by sparks.
