Right now many parents and families are concerned about air quality especially in Southern California. When is the best time to go out and play ? Should we go out?  Check out AirNOW which explains how the Air Quality Index (AQI) works and also allows you to search for current air qualities in your area. There is also a cute and educational section for kids, if you'd like to educate them about air quality and why they can't go outside. There are also some great links to other sites that offer additional environmental resources.
