Light pollution is more than irritating. It's ugly! I'm glad to know that the International Dark-Sky Association is out there working to combat it. There's no reason for street lights or "luminaires," as I'm told the cognoscenti like to call them, to beam upwards. Why people want their properties to be ablaze like Sing Sing is something I don't understand. There's nowhere in Austin that it's dark these days; the sky is pink all night long.
