I'm pressing thumbs for anyone in fire-territory - I've only once seen a heath fire (they're not very common in Cornwall, still less in Oxfordshire), and it was bloody terrifying. And that was in the knowledge that the pastures and roads made fire-breaks surrounding a very small area. The one time I saw an actual forest fire (on the continent) I was having nightmares for weeks. Good luck, and safe evacuation before it becomes urgent.
