Getting to Work

I registered for Pandora (internet radio) in the Bay Area, where I grew up.  Every so often, they’ll play a commercial for California’s ‘Spare the Air’ program, which encourages residents to leave their car at home and take alternative transportation when the local Air Quality Index reaches unhealthy levels.  This index was developed by the EPA and establishes a minimum threshold for when ground level ozone pollution, commonly known as smog, reaches unhealthy levels.
