The heat is on, day three

The hottest day of the year and it's really not the headline. The headline is the fyears first Level Red Ozone Alert. Putting it simply, the air was so bad today it was unhealthy for everyone. We visited an ER in Grapevine where two people were taken early this afternoon. Both have a history of lung problems. A daycare center was full of kids because they weren't allowed outside. The playground was silent and empty. Health experts say if you can pull it off, say indoors. The air pollution is supposed to be unhealthy through Friday.
