The post you are reporting:
If we were to get into what is good art and what is bad art or what is art full stop we could certainly jaw-jaw until the end of days.
But, if we are to concern ourselves with all things 'future' we must surely address the gap between what is hoped for and what actually might happen, whether the baton of hope will pass successfully from one generation to the next.
Involving the next generation in doing only what the present generation thinks is the way forward does not give much scope for the ideas of the generation to come.
Pop-art daubings around the town of, "Come on you whites!" ticks most of the boxes:positive, Dover centric and perhaps even popular, yet such a message could be easily misunderstood.
Leaving Northern Ireland out of it for a moment, gable-end community murals have been, and are, very good ways of bringing the community and the generation together, and of promoting a positivity. Long-term hoardings could play their part here too.
Perhaps Dover is not quite there yet, with your 'Sharks' and your 'Jets':Those that want it neat and tidy and wait patiently for progress to kick-in and those who want to make their mark right now!!
Why not painted scenes of Channel Swims/water sports, local junior football teams at play? Anyway, why not put the question to the youngsters?
