I just mapped Warden Hilltop Community Centre. It has a “green roof” — part of the roof has growing turf, and a trail through it (which would explain how I managed to put a gps trail through the building ☺). How would I tag it?

Green roofs are kind of a thing (and not just ‘cos I briefly worked for Green Roofs for Healthy Cities). I can think of some:

• in Toronto: MEC, 401 Richmond St W, and the Royal York Hotel.
• in Dearborn, MI: Ford Rouge Center
• near Castle Douglas, Scotland: The Green House.
