If you’re sensitive to mold and pollen, you can keep track of the state of the air with a visit or subscription to http://pollen.com or http://weather.com. Weather.com even provides a list of all the local grasses that are making you sneeze; and if you have a problem with ozone and particulates, the weather.com website even forecasts ozone and particulates. You can sign up with both sites to track your allergies, or just keep informed.
