The feces simply sounds like they didn't have working toilets for some reason.
		
		
	 
Well, when WE went camping beyond the limits of the local plumbing system, we took shovels.  You dug a hole, filled the hole, then covered the whole hole.  They had the misappropriated equipment to build a road where they wanted one to be, why couldn't they have spent some effort making several smaller slit trenches for their purposes, rather than one big trench?  
It just strikes me as not a whole lot of respect for the land.  I know, big surprise, they're there for the purpose of getting permission to exploit it.  But that makes me double glad there are laws to limit such people's chances to exploit lands my kids may want to camp on some day.
