Lewisham People's Day
Mountsfield Park, Stainton Road, Catford, London SE6 (0181-852 8020) today 12 noon-8pm, free
It may have been derided for its recent attempts to promote itself as a tourist destination but that doesn't seem to have dampened Lewisham's enthusiasm. Street dancing, skateboarding, ice-skating, children's theatre, workshops, wildlife and story-telling are just some of the things on offer at this annual community get-together. And if it all gets too much for parents there's a quiet zone where they can relax and unwind with a soothing foot massage.
