the best advice i got on the subject of disposal was from a Forest Ranger in Canada.he said just put a good size rock on it.this is wet forest country with heavy winter snow.i tried that on a spring canoe trip and was back in the same camp that fall and of course had to check it out..yes,you would never know...having real TP is a major morale booster which is why you will find a pack in MRE's and some,if not all,military food packs.
