| I am standing under Hammersmith Bridge looking at
something I have known all my life as a Londoner but am beginning to realise
that I don’t have a clue about. The River Thames has been here a lot longer than
the city itself, but it has been keeping its secrets well hidden beneath those
familiar muddy tones of green and brown. On a grey afternoon such as this one,
the surface of the river is particularly unforgiving, and a tentative dip soon
brings me close to fast-running water. This is the sort of stuff that carries
people away to a watery doom and I don’t want any part of that. But I’m here with an open mind at this family beach party in Hammersmith, part of a series of events in South East Marine Week. It is not a beach party in the traditional sense, needless to say, more an opportunity to get a little gentle education.
