Because of the prevailing winds the Hawaiian islands are known to have a sunny spot a mile up the road from a downpour. Wherever there is rain and sun at the same time, there is always a rainbow.
Molokai rainbows are a daily occurrence. Most are double. Some light the sky like a call from some pot-of-gold heaven just over the horizon.
Some are quiet like the hillsides and the people in Molokai.
