Well, WD beat me to this. And guess this is appropriate in that her arguments a while back convinced me to carry out the TP whenever reasonable. In the case of lesser traveled areas, burying everything is not really a problem. However, along the JMT for instance, I find that people think alike in terms of potty spots. I can't count the number of times where I started excavating only to fine someone else's deposits along with TP. Sometimes they look like they have been there for a while. I consider it just all part of my obligation as a steward of these areas ( since I use them). Much of the time I try to minimize my TP use anyway, so I am not usually carrying out much anyway.
