Well, one of my interests was lamp posts / street lights in my teenage years. I knew what models were in use (not names, only shapes), I knew where they stood in my town. Sometimes I did errands specifically to gather information on them. I never was a great information hoarder in my life, though, as usual, fascination was the most important to me, gathering information was only second to it.
