Where do you hide the children's gifts?

As the kids get older I am now faced with a new Christmas dilemma. Where to put the gifts. For the past years it's been easy enough to hide them in a closet or attic as the case may be. Now that they are older, they are getting sharper of eye and we must practice more and more subterfuge to stash the goodies. I know that a lot of you may enlist the aid of neighbors or family members to secret away the magic and I am sure that will soon be a necessary step as the children age. But I ask you dear reader what is the best way to hide said gifts with out actually renting a storage unit for the month of December?
