Yes it does look like a still from Steven Spielberg's Close Encounters of the Third Kind but this is actually Bitts Park, Carlisle earlier this evening.
A perfect afternoon; sun, clear blue sky and no wind gave way to a perfect evening for... fog.
Over 35,000 people made the annual pilgrimage to an event that ranks in the top ten of fireworks displays nationally.
As usual the hugely elaborate bonfire was the first to be lit, in retrospect this was probably a mistake as it turned a thin mist into quite an opaque fog. Still it was very atmospheric and the fog did change colour with great regularity as thousands of pounds worth of pyrotechnics went off unseen in the sky above.
