Regarding the cache, the area is mostly quiet and will allow you to search freely, BUT if you notice the difficulty rating you will have to work hard to log this one as there is only ONE REAL CACHE, you MUST LOG YOUR FIND IN THE ORIGINAL BOOK FOR A VALID FIND.
The house closest to GZ is my father´s so dont worry about any muggles living there, if you see a man playing with a 2 dogs outside it feel free to say HOLA to MAURICIO, MI PADRE
Happy Caching!!
