Removing or altering location signs[1] in a war zone is common but I wonder if that extends to safety signs [2]. There are many there, as far as I can tell. You probably don't want an army accidentally walking though a place like that and spreading radiation to the locals. Given the poaching and looting concerns, I'd guess the sign coverage is quite dense. Anyone visit before?
