Rooftops and Williamstown

So when I was taking pictures from the observation deck of the Rialto, I saw tennis courts and didn't think much about it. Then I realized... they were on the roofs of buildings!


This looked more like a children's playground than anything else. I still think it's cool that it was on the top of a building, though.


Oh! Across this bay is Williamstown. Cool, huh?
