The cold has done some mischief to our plumbing here.
The same laundry room pipes as last year froze up first. Not great, but increasing the house temperature from 20 degrees to 28 degrees C and setting up some directed heaters will (I hope) eventually unthaw that. But then we made things worse.
The massive mechanisms and constructs that keep modern society functional occasionally amaze me. A good example is this story from the New York Times regarding the efforts being made to fix a water leak in one of their main supply tunnels.
