Kaua`i Sky

This past Sat. and Sun. the 21st and 22nd we smelled this unnatural smell. It was all over Kapaa. The sky also looked weird with dark almost circular low clouds and then next to it clear sky with small white clouds. It felt like a canopy of darkness. Any other reports of this and what it may have been? I was thinking it might be the war games but don't know if they were ongoing then?

We cannot live for ourselves alone. Our lives are connected by a thousand invisible threads, and along these sympathetic fibers, our actions run as causes and return to us as results...Herman Melville
