I bought a wagon from Home Hardware when I moved into this neighbourhood and have come to depend on it as much as any suburbanite depends on his minivan. I use it to go grocery shopping, I use it to get Nola to her dance classes, I use it to return my empties . . . but when one of those proverbial squeaky wheels finally gave out last month, the wheels were literally off my wagon for weeks, and I was grounded until I could figure a way to detach the parts that had rusted together, and then find my bearings . . . again, literally.
