Due to the dry and glacial weather brought to you this winter season by La Niña, a Spare the Air Day has been called for today, Wednesday, Dec. 1. This means you're barred from lighting wood fires in your fireplaces, "using fire logs, chimineas or outdoor fire pits," and lighting your toes on fire with a Bic (which sounds so good right now since our feet are freezing.)
