Interesting observation today, reader. While I was waiting for a particular lunch companion, I stood on the corner of two streets. When on the corner, Pivoting left and right reveals not just the street to your left or right, but gives you a view down many blocks. You can also see the same up or down each street; meaning you are in place to view streets in all directions. This forms, of course, a kind of cross pattern, but it also overcomes the tendency of buildings to block your view. Standing in the middle of the street would give you the same view, but of course without the safety of the sidewalk.
I suppose this is the view of the corner-stone.
I SEE ALL AROUND ME
