As a child, we were often told to come in out of the rain. In a national park, however, it’s sometimes best to stay put. Otherwise you could miss out on an experience of a lifetime.
And I’m honored that one of my experiences of a lifetime — the afternoon that resulted in the image Rainbow on Haleakalā — was selected by the U.S. Postal Service to appear on a very special commemorative stamp to honor the 100th anniversary of the National Park Service.
