I can see this roof garden from my office window.
Even in a city like Seattle where trees and moss are threatening to take over every unclaimed even-slightly-damp area, it is nice to see some greenery mixed in to the rooftops. I’m sorry to see they’ve let the grass go brown, but it is winter so that could be part of it. I notice so many other rooftops surrounding it have not taken advantage of their nice flat roofs, either for gardens or just "green roofs" or even solar panels. There is just so much wasted real estate up there it makes me sad.
Hooray rooftop gardeners, where ever you plant yourself!
