I carry a lightweight trowel for the emergency need to poop. It happens sometimes. -- Also, instead of toilet paper, I use a sanitary pad. I start out with a clean one every morning. The new ones have absorbent stuff like disposable diapers that draws urine away. So I can pee and then just pull up my pants and be dry. I throw the pad out at the end of the day.
-- I started doing this after seeing toilet paper blowing all over the place on the camino. My son and I picked up a bag of trash a day off the camino, but I didn't pick up the toilet paper as it was too gross, and I didn't have a pair of gloves.
