i used to dig mine in with a trowel...then i noticed the "locals" doing way more than me and though why not leave it out for the critters...its only poop...its not like we roll in the stuff....
hahaha what about dragging yourself thru the leaf litter with your hands while holding you feet in the air ,....
childish i know, but i still laugh like mad whenever i see the dogs do this,.....
Some good reading here on the matter, Survival topics .com. Tried a link but the naughty poo word was in it.
You could take a look at the Leave No Trace Principles. Or maybe Kathleen Meyer's book How To Sh*t In The Woods, available from Amazon or perhaps borrowed from one of the good folks here on BCUK
