Continuing along on what I thought was the intended route, I had the great good fortune to be called by members of another of the smaller groups who had stopped for lunch somewhat ahead of where I did. It turns out that the way I was going to go would have gotten me pretty wet before I might turn back and try another way.
We did go through a neighborhood unfamiliar to me, whence I got this picture where one can't really see the people at the pinnacle of Diamond Head.
