Tower Grove Park is relatively long and thin. It is 1.6 mile / 2.6 km east-west and less than a quarter of than north-south. Most of the park has a single road on the center of the long axis. It bulges in two places, leaving a landscaped ellipse in the middle. This is one looking east in beautiful late afternoon light. I'm sorry I don't know what kind of trees these are. I'm a city boy. I don't even know when Arbor Day is.
