Speaking of “urban tumbleweeds,” a.k.a. plastic bags and other trash blown through the city, I began to notice back in early spring just how many street trees have some kind of trash caught in them. It’s probably not so apparent now that the trees have grown their full summer coat of foliage, but back then the number was astonishing. Nearly every tree I passed had some kind of plastic bag, ragged rag, bit of orange construction mesh, or other scrap adorning its bare branches, as if this were some kind of fashion trend for trees.
