Most of the time, we have beautiful, clean air here on Oahu.  But every once in a while the wind brings us vog--volcanic air pollution.  (See here or here.)  Luckily, none of us has asthma or other conditions that might make it dangerous.  Things just seem a little more gray and overcast for a while until the wind changes directions.
