I was mostly struck by the quiet irony of the word “plant” on the sign. Only later, when I got [home](https://www.flickr.com/photos/disquietpxl/51353752328/in/datetaken-public/) from my walk, did I connect the orange and white angles on the sign to the angles at the top of the fence, and how the top of the fence casts a serrated shadow on the sidewalk. (Someone on Twitter subsequently [pointed out](https://twitter.com/kaboodlesound/status/1422806241500348416) that the sawtooth could, itself, be a musical score.)
