As everyone knows, this
is a 1950's Chicago bungalow. There are thousands of these all over the city and near suburbs, and it is in my mind the quintessential "Chicago" house. Note perfectly manicured lawn. Chances are there'll be a "[Insert Democratic alderman's name here]/Daley" sign stuck into it come the next mayoral election.
, on the other hand, is the Phoenix ranch. 1960's vintage. Note front carport and lack of grass in the front yard. In essence, it's the same as Exhibit A from Chicago, with a completely different look owing merely to the fact that it's in Phoenix rather than in Chicago.
So, Cyburbians, I offer you a challenge: come up with an example of the house/apartment/high-rise that best represents the residential character of a chosen city. Photos are cool too, because we like to look at 'em. If you have none yourself, do as I did and cull examples from realtor.com or other similar sites.
