A couple of frozen reported in Calgary, but "unknown cause" is sometimes the verdict. One was homeless, the other a woman with Alzheimers who wandered out to the street and was not noticed.

I see my home town of Santa Fe is getting temps down to zero, gas supplies to some northern New Mexico towns cut off because of the freeze to pipelines from Texas, and the utility companies request people to use as little as possible.
People are told to let their faucets drip to prevent freezup. Pipes are buried at shallow depths.
They are buried deeply here in western Canada, but breaks occur.
