Recently, an out-of-town visitor and I went to the St. Louis Zoo. (This is a great place. If you are ever in the area give it a try. Admission is free. Parking is not.)
It was a great day, warm, not hot and many of the animals were moving around, putting on their show. I enjoy watching them from over the fence or behind the glass.
However, my body is getting old enough to demand the occasional break. So this was a welcome sight. So great that they plan it so these are shaded.
