jsd455, Sanitation IS a concern in a world if utilities and trash collection become erratic or discontinue all together!
DH and I have plans to create an outhouse. (a.k.a. privy) We've stockpiled lime to help control the fecal matter.
As far as personal hygiene, we're avid campers and are equipped to create an outdoor shower. We also have a large supply of baby wipes and supplies to make homemade wipes to keep clean in between, if the old "bath on Saturday night" returns to our society!
Burying or burning your trash is another option but what about your neighbors? In the event that trash begins piling up I suggest a large stockpile of rodent and insect poison. At least you can TRY to keep your home and property from being invaded.
