Locked Public Tennis Courts

I went for a jog this evening and passed some public tennis courts. It was a beautiful evening, the sun was shining, it was a nice temperature but all the courts were empty. The courts were locked! There was a very high fence round them.

I continued my jog and a little while later I saw a couple of children playing tennis on a road. They had no net and indeed no protection from on coming traffic. There weren't too many cars on that particular road and I guess the kids assumed that if one came round the corner they'd probably have enough time to get out of its way.

As a consequence of having locked courts:
* Fewer children in the area will play tennis than would otherwise be the case
* Bored children will get up to mischief rather than play tennis
* Children who do want to play will risk their lives by playing on the road
* Other children who really want to play on a real court will risk their lives by climbing over the high fences which are round the courts, since the gates are locked.
* Those that have the power to lock the courts will get a kick out of the fact that they have the power to prevent children playing.

From an insurance point of view, how can a child be allowed run through a park but not allowed on to a harmless tennis court?

I reckon the people who locked the courts are not stupid, they are just very poorly motivated.
