Geoff has done the math - "I was out the other day in a kind of sports 'r' us warehouse and looked at a 90 litre rucksack which was just under £100. my immediate reaction was that this was bloody expensive per litre. trying to prove myself wrong i worked out that the flat i live in is about 230 cubic metres which would equate to 230,000 litres i think. this works out at £253,000. scarily i would guess that this is exactly the current market value of our flat.

Conclusion: people who say camping is cheap are fooling themselves and getting wet in the process".
