I finished the end of my turkey sandwich just as the train pulled into the aquarium stop and applauded my good, full timing. I hustled out and after some dithering at the admissions counter over the 4D Planet Earth show combo value ticket (Do you want the total experience? asked the woman at the counter. The answer was yes.) I hurried in and grabbed a soft serv cone at the snack bar to eat while watching the walrus feeding. Unlike me, these second-largest pinnapeds eat 70 pounds of fish a day.
