I make sure to take care of any business before leaving for the woods. Once there i dont eat much so i dont have to worry about a second round while still in the woods.
This method works well but is not entirely perfect, once i walked the 1.5 miles back down the mountain and back to camp cause it was way too cold and on another occasion i left a couple flannel sleeves in the leaves. on a side note, i wish i had the cash to afford flannel TP all the time
