Watching the news today when a predicted storm hit the UK and has deprived large areas of electricity supply, I reviewed our emergency preparations.
We are lucky. Parked beside our house (unluckily so a few years ago when a shed fire caught the caravan which was destroyed and caught the house) is our caravan. We keep two batteries charged and at least one full gas bottle. In extremis we also have a portable petrol 240v generator which can be connected.
So in the event of an extended power cut we can decamp to a cosy, heated environment with built in radio.
If all else fails, we also have a portable wood burning stove, a charcoal brazier and plenty of firewood and charcoal, with a large enough canvas tent to accommodate both, complete with beds, blankets, hot water bottles and cooking equipment.
Sometimes the hobby of travelling around the country and dressing up in historical clothes to live in the past for a weekend can have modern world benefits.

Another benefit is that a wool-lined wool knee length soldier’s coat can be very warm indeed. We have several.
… As Berlusconi famously said ” pretend you are on a camping holiday”. Happily, I have plenty of surplus podiatry magazines to burn to keep warm 🙂
