Modeling buried wire

I was wondering if there was a way to represent a buried conductor without it just looking like a pipe and not spend all day trying to draw arcs in three axis to do it.

Suggestions anyone?
I tried using 2D freehand tools as well as the SU free hand tool with no luck.

In the image it is the horizontal runner I wish to add some randomness to its look. The vertical pieces are intended to be straight sections of rod.
