For those of you in London and the south east;
map of the assembly point which is on the Wandle trail opposite the cul de sac on Waterside Way.
This cleanup brings us back to Plough Lane, SW17, to tackle another 50m of river downstream from where we got in at our December cleanup: the river at this point has so much rubbish in it that to break the back of the problem, we need to visit it more than once a year! more info at the Wandle Trust website
