Query: Humanure Handbook

Are you "Disaster Prepared"? Do you have your water, canned foods, coleman stove, flashlights, duct tape, medical kit? Good for you! Now, what will you do if the water pipes break, or the sewer lines are clogged or severed? How will you flush that toilet? This is a topic no disaster preparedness materials ever cover! And it is, indeed, a very important and potentially hazardous area of our existence in a disaster. I bought this book for just that purpose - to help me properly prepare for this portion of our survival. Not only has it helped me in that area, but has also given me a tremendous amount of other valuable information. I highly recommend that everyone read it!
