Sometimes there is a lot to see behind buildings. My walk today, took me to the back of one building where I saw a standpipe arrangement different from others I’ve seen. This dual set of standpipes was just below an alarm bell. I suppose the fire department would locate the standpipe by localizing the sound of the alarm. In this case, however, there isn’t a lot back there to distract them.
