Here's a photo which depicts the truth of the skies of Maui. Not only do the people suffer--as do most of the Hawaiian Islands and especially the Big Island-- from volcanic smog, but we also have the smoke from sugar cane burn blowing in the wind which is full of chemicals. Of course, these two conditions don't happen all the time! Lately the Vog has been horrible, but thankfully no cane burn is blowing our direction today.
The Vog blows over from flowing Kilauea on the Big Island. The cane burn originates from Central Maui.
