Sir – I wrote to you last year about the state of South Park during the summer months when the evening and night users of the park left it in a relentlessly disgusting state.

You might be interested to know that things have started early this year, and that the last few days have scored several of the year’s firsts, viz the first disposable barbecue, the first multi-bottle party and, inevitably, the first pile of human excrement in the woodland. I’m looking forward to the warmer weather already.
