Anti-social and nuisance behaviour, although not common in St Andrews Park, has become an increasing problem in the summer months, particularly for those living on the roads immediately adjacent to the park.
Presumably this is a phenomen common to other Bristol Parks because Bristol City Council is considering the revival, reviewing and reinstating of byelaws. It wants to consult on this and there is a survey which you can complete on the Council website at: http://www.surveymonkey.com/s/parksbyelaws
Note that this consultation closes on 13 September 2013.
