A great deal has been written about celebrity trash. Literally. People who sifted through Bob Dylan’s garbage for years then documented it. And no doubt kept a few souvenirs. Hard to believe? At one point I lived in Cambridge, Massachusetts, around the corner from the homes of both Tracy Chapman and Marianne Faithfull, and I can assure you that scavengers would regularly sift through each of their garbage cans looking for mementos. And while the pastime holds no appeal for me, I have to confess that I was fascinated by this particular splayed-open garbage bag I walked past in Montreal a few years ago. Hundreds of oyster shells. On a small residential side street far from any restaurant or seafood market. What was the story, I wanted to know. Party trash? What? I’m only surprised that the pile hadn’t attracted all of the neighborhood cats. Or maybe it had and I just happened by too late.
