One of the sub-mysteries of the protractors is the location of No. 196, seen in the top image from a website about Bloomfield graffiti. This afternoon I found the location, but not the protractor. Whoever removed it did so cleanly. It didn’t even leave a ghost.
Mark found two runs of protractors on the Bloomfield Bridge, one that started at No. 139 and another that started at No. 204. I grabbed shots today and enjoyed the idea of the Grand Protractor crossing the bridge on two separate occasions, maybe weeks apart.
I also snuck behind the columns holding up the bridge, one of the graffiti hotspots of Pittsburgh. For a brief moment I expected to find a protractor altar, an array of them pasted in the shape of a giant flower, twenty feet high. But I didn’t find any back there.
