You know, it's not illegal to take a dump- but it's considered pretty
offensive to do so on a crowded sidewalk.

Yes, laws are funny things. IIRC, it is illegal to empty your holding tank
into the anchorage, but perfectly legal to stand at the rail and empty your
bladder into the same anchorage (barring discussions of exposure or
disturbing the peace, etc., of course).
