Three years ago, we were hiking the Old Saddle Trail section off the Mule Deer Trail in the White Tank Mountain Regional Park. At a trail intersection, we met Chuck and his horse. He stopped to allow us to cross in front of him. We stopped and visited for a few minutes. I asked if I could take a photo of him and he obliged.
About the photo. Captured in April 2015 on my Samsung S5 cellphone. F/2.2 1/750 sec, ISO-40. I was intrigued by the black mask on the horse and had to ask. I was told that it’s simply a protection from flying and biting insects.
