My wife says that I collect cords. I do have a bunch of patch cords for connecting electronics, old and new. In my youth, I collected cars like matchbox. In my single digit years, I loved trucks; semis, dump, pickup (scale models of course).Besides dust, that is! lol
Many people "collect" items....pens, guitars, salt shakers, glass figurines, books, shoes, etc. What's your interest? What do you collect?
