Bless the internet for showing us every strange/interesting hobby in the universe.  Is This Your Luggage is a website that shows one humans lost luggage collection.

I COLLECT LOST LUGGAGE, PHOTOGRAPH IT, AND THEN TRY TO FIND THE OWNERS. IT’S A LITTLE ODD BUT NOT AS ODD AS STAMP COLLECTING, JUST A LITTLE HARDER TO FIND STORAGE SPACE.

Note:  They buy the Luggage from Auctions, because apparently after a certain amount of time the airlines give up on trying to find the owners.
