i must admit i haven't come accross one for a long time, (like 20 years!).
I wonder what they do now, mind you they all seemed close to retirement age back then (but so did anyone over 30 back then!)
I have noticed the park in Inverness seems to have its gates open most of the time now, when ever i go back. Who's going to tell the children to get of the swings once they pass age ten years ( the most common parkie shout as I remember)? ;)
