I know what you're saying, B2R, but there's a lot the kids can do and, in general, do in a far safer environment than many places. In many cities, for example, the kids play tick with bricks and it's not easy for youngsters to do a lot outdoors, even if their outdoors were enticing, which many aren't. Now, I don't deny they need some leadership, which is the job of parents, but there are also a lot of opportunities for youngsters with local organisations, such as Scouts, Guides, Llandudno Youth Theatre, Churches and youth clubs.
But if we take a quick look at what they can do relatively safely in Llandudno, it includes
Swimming
Cricket
Tennis
Football
Sailing
Climbing
Walking
Photography
Skate boarding
and then the indoor pursuits include
Table Tennis
Roller skating
All manner of games
Snooker
Billiards
and a lot more I've not listed. Youngsters need leading, challenging, engaging, teaching and encouraging. Moreover, they need to be in socially conducive situations, which is what youth clubs, Uniformed organisations and churches provide, although I accept some are better at encouraging youngsters than others. If there is validity in your observations, I suspect it lies with the churches.
The Methodist churches in particular originated with the idea that people from any social class would enjoy social events, and that's how they came into being. I don't know how well the current St John's continues that great tradition but in general the church buildings in Llandudno, which could provide so much for youngsters, seem remarkably free of them.
Perhaps the various Church leaders should be openly challenged to say what they're doing to work with and for the youngsters of Llandudno?
