Image: Lost rivers of Manhattan (via Urbablurb)BLDGBLOG links to an old Urbablurb piece on fishing the underground streams of Manhattan. From the Urbablog post:
One day I was curious enough to try my hand at fishing. I had an old-fashioned dropline and baited a hook with a piece of sperm-candle. I jiggled the hook for about five minutes and then felt a teasing nibble. Deep in the basement of an ancient tenement on Second Avenue in the heart of midtown New York City, I was fishing.
