The problem with hiding things in my garage, is that would mean they are important enough to hide. Anything that important doesn't belong in a garage environment, especially not mine. Between fumes, over-spray, oil, grease, fire, and any other number of solvents, I seem to ruin everything that comes near a project, except the project that is. Heck, I can't even pump gas without getting dirty. I don't particularly care for hiding things in the attic either, as it too invites pest and all sorts of other things. Plus, with as much stuff as I have in my garage, it would only serve to attract thieves to it... again not a good characteristic of a hidey hole. I do have a hundred year old safe in there right now, but it is only so I can refinish it for my wife.
