Would you subject your home to this level of risk, asks a pipeline critic below.

I feel qualified to answer.  My parents' house, in which I lived for twenty-five years, is directly across the street from the path of the Rocky Mountain pipeline through Edmonton, and about two blocks away from where it crosses a ravine -- suspended on a bridge, in the open air.

Not once did I worry about a spill. Nor are property values a problem.  The neighbourhood is definitely one of the good areas of the city.

So "would" is the wrong word.  "Have subjected", gladly.

In Vancouver, I'd rather worry about building codes and earthquakes.
