Did they do thaaaaat? Obsessed fans try to find Urkel's house

Even though I'm guilty of watch the show, I've never gone on a hunt to find the location for a particular TV show. Not that I wouldn't, I just haven't yet.

Is the Winslow place "one of the most recognizable sitcom facades" as the narrator says?
