Another thing to keep in mind , depending on what your preparing for , is to only have SOME of your gear in your house , have other places or stashes away from your home , that way if they do find something , your not out . I worked in the theming industry for 25 years , making exhibits for zoos , natural history museums , theme parks , etc . I could tell you how to make things outside that look so real , you wouldnt know they were fake if you were standing on them . Here is a hint , you do 50% of the work , and nature does the other 50% , they wouldnt know it has not always been there . Lot of things you can do if you know how , just takes planning and some cash .
