An interesting coincidence example from Pat McLoughlin plus one of my own.
When I had finished setting up this post it was time to have something to eat in the evening. Feeling lazy we put the television on while eating - okay I know it's not a good habit! - and the programme we watched was Great British Railway Journeys. By coincidence the places they travelled to were Betws-y-Coed and Blaenau Ffestiniog as mentioned in the above story. They are not exactly places you hear very often on television.
