If you want to build a crafted safehouse, this is a nice spot (http://pzmap.crash-override.net/#0.6270698299910458,0.08305693486254942,360.3656307129799). Of course it is relatively far away from the inner city, but you have a low amount of zombies there and fishing is an opportunity. I liked it to build my own house out there, although it got boring after a while, since I had killed all zombies within this area. So if you want to live in the "wilderness", I would recomment it
