I have a few litres of water in bottles due to a main water pipeline fracture earlier this year, we were told not to use the water for drinking as it had become contaminated from drawing earth into the water pipeline. The fracture was fixed in a day or two but it took a while for the water to run clear due to header tanks in loft spaces being filled with the contaminated water.
Tins wise, we always buy too much. This is something I talked to my wife about seriously, explaining that if a problem arose such as a petrol strike (remeber the last one and the panic buying?) or another flood we may have problems getting food in local shops. I own an optimus nova+ and have a diesel car parked out front that I could drain fuel off of to keep it going if needs be. The car is filled up and rarely used at the moment, I think the last time I used it was when I went to the Midlands Meet!
We don't have enough flour or sugar, that much I know for sure. We both drink tea and the girls can have a small cup once a day if they've been good (they like a nice cup of tea and a biscuit!) and so we do go through sugar and milk like thgere is no tomorrow. I have powdered milk, but not lots, just enough to keep going for maybe two days if we take it steady. Have a fair supply of porridge oats, rice and beef jerky! Plenty of spices, herbs and bouillon/stock cubes, maggi, and other things to help make a meal slightly more interesting, and I also have permission on two farms and an air rifle! Might have to get a break barrel rifle though, PCP air will run out and I still haven't got my dive bottle filled up yet!
Good thread, I'm not one that buys into TEOTWAWKI, you would be herded up by the Govt/Armed Forces and put to work to supply the food required for survivng members of the Royal Family, etc. There wouldn't be any wandering off into the sunset with a packed horse and your family in tow.
