Cathy and I took a walk this evening and enjoyed an occasional view of the sky. Our neighborhood has well established trees, having been built up about 50 years ago. Different parts of the neighborhood have different street trees and some of them have lasted better than others. Many of the original red oaks (Quercus rubra) are gone, while others are very healthy. The willow oaks (Quercus phellos) are more uniformly healthy and generally quite large. There’s one street I call the cathedral because of how the willow oaks form a Gothic nave over the road. The maples (mostly red maples, Acer rubrum) are at the other end of the spectrum. Some are fine but most are less healthy or have been removed. There are sycamores (Platanus occidentalis) scattered around and they are generally healthy, as well. Anyway, the link between the trees and this photo is that the trees mean that most of the time while walking we don’t get an uninterrupted view of the sky.
