I went on to the Subways/Transit/Traction forum yesterday and looked at a video from the 1950's and 1960's subway system in NYC. It was entertaining because, as well as the clean graffiti free subway platforms and tracks, the automobiles of the era were also shown in the video. The apartment houses also had the many, many TV antennas fastened to the chimneys and sanitary sewer vents on the roofs. There were as many antennas as the number of apartments in each of the buildings.
Does anyone include antennas on the roofs of their structures?
While I am on the topic of roofs; does anyone model pigeon coops on their roof tops?
