Assuming that you have followed the sage advice of this site and are adequately provisioned, this would be my biggest concern. In the event of even limited social breakdown, "good" people can do awful things if driven by fear and desperation. You may want to consider ways of utilizing your resources that draw the least amount of attention to the fact that you have what so many others need to save themselves and their loved ones.

The smell of cooking food will advertise your prepardness as will waste water poured into the street in front of your home. If you use a generator, it better be very well insulated for sound. Something as simple as the beam from a flashlight can act as a beacon to those who would forcibly relieve you of your essentials if the store shelves have been empty for weeks and precious resources have long ago been used up.

I hate to have to consider the scenario, but in the case of any large scale disaster, the wise ETS member will have added home and provision security to their plans and equipment.

I'm certain there are other (and better), ways to camouflage our resources. I'd love to hear what others have come up with along these lines.
