I'm not sure why I took either of those pictures. I had just walked away from John and Marion, I was heading back towards the creek to try to recreate the pictures I had taken the first time I went there (that's a whole other story!).
It looks to me like a man walking along the path behind the fence (and yes, it's facing the pond) who is carrying a bag of some kind, and is touching his right hand to the brim of his hat. I do not recall seeing another person dressed in such a way that day, and certainly not at this point in time. It was pretty busy there about 30 minutes after this picture, but we still had the place mostly to ourselves when this was taken. There is something else in that picture that always caught my eye when I would look at it, which I suppose is why I never saw it before. I don't mean Something Else, just leaves playing tricks on me
My daughter has been having a field day mocking me over seeing stuff in pictures all the time, but even she was stymied by these.
