While not what you might call a good read in the Stephen King sense, if you have an interest in composting toilets and boats "The Humanure Handbook" is a serious must read...What's even better is while you can buy the book if you need to have a "real" book but if you are ok with reading it on your computer you can download the whole thing for free as a PDF.
We've now had our home brew composting toilet on "So It Goes" and it is working out just fine. No muss, no fuss and no smell! Throw in the bonus of one less thru-hull to have to worry about and it is a winner all around!
