I have known this woman over half a century. Half of that, I thought she was fearless. She just about is. You've seen her Normaphotos of wild creatures who allow her to take extreme close-up portraits without sensing any harm in her.
There is no harm in her.
There is however a fear in her. So, when she went out to film a clip of glowering clouds, I stood at the back door and waited, waited to fling it open in a hurry. Please crank up the audio and view this 27-second clip. It's long been one of my favorites.
Thunderation! It is, so far as I've determined, her only fear.
