This is in my prepareness manual:
Emergency Toilets & Garbage Disposal-by Alan T. Hagan
I also keep a rolling bag with canned food, instant oatmeal, instant COFFEE, packets of water, dishes, canned heat, Sterno stove, eating utensils, etc., close to my front door. There is enough food/water in there to last a week. The rolling bag goes with me if I have to leave.
