The Indianapolis area, and downwind counties, have an ozone alert today, which they call a Knowzone Day. When hot weather combines with a stationary front, the stuff from local pollution sources gives us more ozone than is safe for children and folks like me with breathing difficulties.
The Knowzone notices tell us to stay indoors, restrict motorized travel, and not mow or fill gas tanks until after 6:00pm. I don’t entirely understand this.
Isn’t ozone a gaseous form of oxygen that can’t be escaped by staying indoors? Do they just want to avoid having me do my coughing out in public?
