>>2496546dig a hole about 6 inches deep with a spade and shit into it. i typically just use my standard alcohol sanitary wipes instead of toilet paper. i also usually just add the used wipes to my carry out trash bag. doesn't take that many to clean up; maybe two or three sheets because they're made of thick paper and soaked in alcohol. it's also not very likely that you'll shit more than once per day while /out/ so it's a negligible amount of trash in terms of weight or portability.
