Wow.... that shot makes my soul long to witness it in person.
I love the story that goes along with it. Maybe I should start a petition in my state to turn the lights off so we can purge our evil spirits. Kind of vindictive of them to send them off to the other island though!
It's an amazing tradition. And yeah, why not? The whole world should do it one night. Imagine what we would see then! Assuming there was no moon and cloudless skies ;)
But even just the energy saved would be HUGE!
And who knows, perhaps all those evil spirits would head off in the direction of the brightest star :)
