I figure I can "bug in" for about a month with the wife and kids and current supplies. Hopefully that amount of time will be lengthening with further prep. Except.... I don't have a great plan to deal with solid human waste. Do have a toilet seat that sits on a 5 gallon bucket, some cat litter to cover odors. What to do with it from there? Home is in a typical suburb with houses on all 4 sides with sewers/city water. There is a drainage creek in the back, which would be an intermittent water soure (filtered and/or boiled of course). Thoughts?
