Things break. You can't really plan for an individual pipe where it's going to break, when it's going to break, if it's going to break. What we do plan for is our response to repair.

When things break down ... he can pull (the ball) down and make something out of nothing.

No matter how carefully you plan your goals, they will never be more than pipe dreams unless you pursue them with gusto.

Sometimes there could be a rock sitting there, and say, oh gee it was resting on that rock, but really we didn't see any of that kind of situation, so right now we're just looking at the pipe.

A section of pipe split and kind of went around the pipe this way. Typically this is a very stable, very rigid, very strong type of material.

All representations of a thing are inherently abstract. It´s very clever.
