Think of me when you are getting your colder weather. We've got -20 in the forecast for Sunday night, with high winds so the wind chill will be a lot lower. When it gets that cold, the garage heater sometimes shuts off so we have to monitor that. My sewing area is right above it and don't want any frozen pipes. The bright spot is that we get temps that cold most year, so the infrastructure is made for it. Get a kick watching building shows that are down south, and they talk about the water line being 12"-18" deep. Here, 4 feet is considered minimum and most go closer to 6' down.
I'm so hopping this is our last winter in the cold north - I'm not going to miss it.
