How was your trip in Mexico? Yes, I guess talking about toilets in the woods has degraded. I once asked the question about bathing and that went to another level. Down.
When your alone it's not a problem. When your with other people you don't know well or with women. Sometimes you need or they need a little privacy. Maybe in the form of some kinda cover. I was thinking of using my hammock fly to construct some temporary screen. As far as a toilet. Leave the TP and trowel at camp so you know it's occupied when the necessary supplies are gone. I guess when your alone in the middle of mexico wilderness. None of that is an issue.
