That’s what I was told. (The photo was definitely taken in Moss Beach: everything is embraced by the fog.)
Notice, also, the way the chairs are made, the arts & crafts look, and compare them with the photo in the post below about Fanny Lea & Frank Torres. In the first photo of that post, the woman stands in front of a fence that strongly resembles the chairs in this post occupied by Mr. Wienke and his dog friend. Who made the chairs and the fences?
