As I walked to work this morning, I saw some sad news in the windows of The Museum of Useful Things and Black Ink @ Home just down the street from me: it (they?) plans to move to 49 Brattle Street in Harvard Square sometime this spring. I’ve always been happy that an actual store selling interesting, well-designed stuff is located only a block away. I only bought a few little things there – it was always more like “The Museum of Things that Make Me Wish I Had a Place of My Own” – but it’s a great part of the neighborhood. So Black Ink used to be located next door, but then moved in with The Museum, which is apparently a “division of Black Ink, Inc.” Intarawut, which seems never to be open, moved in in its place. Then another Black Ink moved into Harvard Square, at 5 Brattle next to that deli/diner place I’ve shied away from since I went there with Sloan in college. And now The Museum of Useful Things is apparently packing up and moving in around the corner from that new-ish Black Ink on Brattle, though on my walk to the A.R.T. today, I noticed that 49 Brattle is the home of Colonial Drug, a Harvard Square institution. Are they leaving? I guess nothing’s sacred, as a 137-year old family run sporting goods store located on the same street plans to leave at the end of the month. Why is rent so high, if there’s not enough traffic coming by to shop?
