Yeah, it was an absolute bargain with or without power. I'm going to be running on gas and battery for what it's worth.
We also probably won't be sharing the rally field with anyone, (though there was that poor couple that had to put up with us last year!) so BBQs and a reasonable level of music and light pollution will be just fine.
Matt, buy an LED torch with a hanger if you haven't got one already. It's a long walk to the toilets/kitchen at 4am.
