When we moved into our house more than a few years ago, one of its selling points happened to be a relatively recent conversion to natural-gas heat. So much cheaper than oil or electric! … at the time.

Now, bills with LOTS of digits come sailing through the mail slot. And that’s just for the “average” winter temperatures we’ve had till now. Suddenly the big chill is upon us, the cars are frosted, my toes are frozen, and I can see far enough into the future to envision my first $200 heating bill spitting out of a PSE printer somewhere.
