Rachele Rosi-Kessel offers photographic proof that at least two deer have made it to the center of Roslindale:

How they managed to get to my yard, I don't know. Our house borders the train tracks and then the Arboretum, but there's a tall fence between the two. There is a small hole in the fence, but it seems too small for deer to fit through. Yet somehow, here they are!
