The wildfires devastating much of Canada right now are sending their smoke south, and many areas have been badly affected. The more vulnerable among us must be very careful. Though today is relatively clear, for the past several days, I’ve had windows closed, the air conditioner in the bedroom running, and fans circulating inside air. The skies were yellow, air thick with smoky haze, and even though the fires themselves were hundreds of miles away, it smelled like they were right in my backyard.
