We've just set up a Friends of the park group in our local area to help try and address this. Its early days and at the moment we can only do simple things until we find our feet. But we did a deal with some of the kids in that if they left the bowling green alone (vandalising it) we'd get some football organised for them (which is what they want). We've got some local community police officers to help run things in the autumn. The bowling green and pavillion had fallen into disrepair through lack of use for bowls and vandalism but we've decided we need to keep it as it represents a focal point on the park. Volunteers along with the council have begun repairing and playing 'fun' bowling events twice a week (we also get a handful of kids who come along as well and are actually enjoying it). Eventually we hope that the building will house a ranger (our next campaign), bowls club, cafe and other activities --- it was a simple gesture to keep it up and running as we felt if council demolished it we would lose our focal point and a way of generating more activities for the community in the future, and hopefully there will be a knockon effect re antisocial behaviour. Its hard work and as I said early days and it may not work in the long run but I guess we have to try.
