Interesting; when I moved into my new house, the first project was to fix up and seal the old shed, so that non-garage junk could be moved out of the garage. Rebuilt the door, painted it inside and out (sprayed Kilz oil-based on the inside), caulked the interior edges, and added a small stone walkway so that items being transferred out of the shed wouldn't be placed on the dirt.

My only regret was not more thoroughly documenting the contents of the various shed containers. I should've marked each storage container with a large number, then maintained a simple computer text file that listed the contents of each marked container. Then when we wondered: "is it in the shed?", I could've just checked the text file, and determined the exact container that housed the item in question.
