LD, others here might have heard me talking about this before, but you might have missed this:
During WW2 my Mum's best friend's father was a farmer, so they were usually the only two to arrive at dances and parties by car, all others had to walk, cycle or use public transport, so arriving by car was very special. He got his extra petrol and could drive anytime, anywhere as long as he hitched a trailer to the car and put a pig or sheep in it, so they always arrived with livestock behind!
