Pittsburgh's housing stock is probably my favourite in North America. The way all those row houses are integrated into the hillside fascinates me every time.

Ahh, the Southside rooftops. I've been drunk, sipping beer and/or smoking weed on more than a couple of those rooftops on a warm summer night. With the massive glowing "*insert brand name here* Clock" on one side and downtown glowing on the other side... A beautiful sight.
PS - Looks like that skinny yellow house with motorcycle has a female owner, judging by the multiple Hellno Kitty stickers. That's hawt.
