David, always nice to see your images--and this one brought back a memory.
When I was a child, a long time ago, my grandfather had a ranch about 30 miles outside the park--so I sometimes was able to visit. Not far from this this "location" I once saw an older white-bearded "guy" with a large view camera on a tripod patiently waiting the light, and even then I imagined it was that "guy". I'll never know for sure but I like to imagine it was. I'm sure though--he, whoever he was, could have told me what I was doing wrong with my little camera...
