Cone Amnesty

At the end of the month, we have Hay Festival, and every year traffic cones go out all over town to stop people parking along the approach roads, or other places where it's not safe or desirable to have parked cars cluttering up the place.
Last year, fifty of the cones went missing, and now the police would like them back, please! Gareth Ratcliffe has announced a cone amnesty for anyone who happens to find one.
