Mike, I'm going to follow Justin and bring TP with me as a backup on my next trip, too (Weminuche in July). I am willing to try your techniques. If I find they work, I will give up bringing it too. I gotta say that the section on how to clean your butt is worth the price of your book alone:) I never thought that would be a subject that would blow my mind!
But about the bandana….don't think I can give that up just yet. It's headgear, camp towel, pot holder, coffee maker (coffee supposedly is a natural mosquito repellent) and potential first aid bandage all in one device. I would need strong convincing to give it up.
