Here are 5 standpipes (or sets of standpipes) that have caught my eye. Some caught my eye for their reflective shininess, and some for their weathered patina.
2009
2010
2011
2013
2014.
As I put these together, I saw that the 5 photos were neatly from 5 different years. (I had a 6th photo that was also from 2011, but it didn’t fit as well, so I didn’t include it.) Would you believe that it bugged me that I didn’t have a standpipe photo from 2012? Further, I noticed that it should have been of a weathered (rather than shiny) standpipe, in order to best complete the pattern. I actually started to look through my photos from that year before realizing that it was crazy to do so, especially given that I have more work to do tonight before bed, and it is after 11 p.m.. (This is the sort of compulsion that I’m talking about.)

This is an interesting set. And I can understand your dismay at not having a 2012 one.
I’ve never seen such a shiny standpipe as the one in your 2009 photo. But now that I think about it I realize that they all must have been new at some point. Cool set of photos… even if they’re not quite up to your exacting standards. I like ’em.
