I like to go other places to think. I'm lucky because I live on the coast between a mountain range and the sea, so I have both beach walks (which are gorgeous at this time of year) and mountain hikes to allow me thinking and planning time.

And there's always sitting in the waiting room at the dentist and so on.

I just had a sudden unexpected new idea for a completely different story. Not sure whether to leap on board and see what I can do with it, or not. It's taking a legend (the story of Branwen from the Mabinogion - http://en.wikipedia.org/wiki/Branwen) and playing around with it. I'm not sure how yet, so it might be something to keep for another day, but it just popped into my head.
