gone on the river
One of the interesting things about traveling on a river is that you see the "backs" and "undersides" of a lot of infrastructure that people mostly observe differently. It's kind of like riding the Amtrak in this way. Where we used to orient buildings, public spaces, public architecture to the river (and train), we now almost exlusively orient them to streets.
One of the seemingly unavoidable consequences of this hiddenness, this orientation away, is that you see a fair amount of graffiti from the water. The riverward side of walls, infrastructural buildings, bridges. Anywhere someone could hang out for awhile, out of sight of most people, and scrawl something in spray paint.
I found this particular little bunker pretty hilarious, especially the "we've been trying to reach you about your car's extended warranty."
