Residential area, the garden is maintained by local volunteers. An easy walk in a nice neighborhood. Please be careful around the flowers. Many muggles about, pretend you are admiring the plants (you may not have to pretend). The Silver Maple growing there was raised from a seed by my Father and I transplanted it here when I moved into the neighborhood. Years ago in winter the neighbors used to build a short snow wall around the triangle and then flood it to build an ice skating rink. This may have the distinction of being the smallest city block in the city.
This can be a little harder to find after it rains.
If you see the crazy people with the giant dogs across the street wave at them, they're mostly harmless.
