Usually what goes on in those places is more than possible disease transfer...sometimes the disease gets to the happy ender other friends...sometimes robbery...wounds...blackmail...extortion....it is not that harmless....broken relationships...vermin...etc....if you go...you are like a cattle for slaughter....if you follow your impulses folks be waiting to rip what they can off you...count on it...
