On a sloping promontory on its wooded north shore was a modestly sized building called the National Capital Exhibition, and I called there first, more in the hope of drying off a little than from any expectation of extending my education significantly. It was quite busy. In the front entrance, two friendly women were seated at a table handing out free visitors' packs - big, bright yellow plastic bags - and these were accepted with expressions of gratitude and rapture by everyone who passed. "Care for a visitors' pack, sir?" called one of the women to me. "Oh, yes, please," I said, more thrilled than I wish to admit. The visitors' pack was a weighty offering, but on inspection it proved to contain nothing but a mass of brochures - the complete works, it appeared, of the visitors' center I had visited the day before. The bag was so heavy that it stretched the handles until it was touching the floor. I dragged it around for a while and then thought to abandon it behind a potted plant. A here's the thing. There wasn't room behind the potted plant for another yellow bag! There must have been ninety of them there. I looked around and noticed that almost no one in the room still had a plastic bag. I leaned mine up against the wall beside the plant and as I straightened up I saw that a man was advancing toward me. "Is this where the bags go?" he asked gravely. "Yes, it is." I replied with equal gravity. In my momentary capacity as director of internal operations I watched him lean the bag carefully against the wall. Then we stood for a moment together and regarded it judiciously, pleased to have contributed to the important work of moving hundreds of yellow bags from the foyer to a mustering station in the next room. As we stood, two more people came along, "Put them just there," we suggested, almost in unison, and indicated where we were sandbagging the wall. Then we exchanged satisfied nods and moved off into the museum.
