I found this sign quite curious. It is new, but it refers to an idea that existed on the Beltline for a while, the Atlanta Beltline Arboretum. This particular sign speaks of protecting eastern Hemlocks. What is so important about them I am not sure. But they are important enough to make a sign about. You can see my shadow in the picture, I was trying to get out of the way so the sign could be seen.
