Karen, I'd forgotten how old cities can get - even in Canada, a younger country, there are a lot of nasty old pipes in the older cities such as Toronto and Montreal...and nearby Calgary ain't no picnic either! Money to upgrade infrastructure is always being demanded by city mayors. To digress - it's not just water pipes. Last year a bridge "broke" in Quebec; the fallen concrete killed a young woman in a car. Her fiance, sitting beside her, survived.

There's a lot of work to do.
