Walking downtown when I was young, I always wondered about what was under the manholes. An ocean full of tropical fish? Perhaps a tunnel that opened up to the other side of the world. I remember if leaned down my head towards the hole, and listened very carefully, I could hear the sound of gushing water, like an waterfall. Today, though I am not as childish as I was years ago, I still like to imagine thousands of tiny fish swimming away as fast as their fins can take them in a magical ocean underneath the manhole covers.
