Lock down.

One suggestion, worth thinking about, mentioned in a preppers book is staying hidden. By that I mean they suggest that if you've decided to stay in a place visible - say in an urban environment - and you're well prepared come what may, then allowing one and all to see your working lights, water and food storage is a mugs game.

It takes two forms.

In the first by allowing neighbours etc to see how you prepared ahead of time you've made them aware that you're the go-to guy to 'borrow' stocks from. Share if you wish but if you do not then stock pile with half an eye on NOT letting all and sundry know what you've got. So later night or super early deliveries, small amounts built up over time and the like are the way to go. Ditto buying from a town over rather than locally.

The other form is post shit time. Don't have your noisy generator outside working away and powering visible to one and all lights and heat. Use smokeless fuels and filters which keep any such energy generation down.

So blackout blinds and silent running generators are a must. 

A third form, not often considered, is staying hidden by joining those remaining. In other words it's suggested you make like your as fucked afterwards as everyone else. Hell one could even argue that the ability to top up your stocks with whatever you can scavenge is, in fact, a good idea. So a scouting of local food sources (shops??) after the law fails (best avoided before for legal reasons) and assuming no one else has beaten you to it is one to be considered. Remember, as always, rotation. So if the local Bookers warehouse has food left get in there!! You will, of course, need to use the lock down rules. Do not think that, post SHTF, you dragging a ton of food back to your refuge in an urban setting is not going to be noticed by those going without around you.
