I have pleasant childhood memories of my father bringing home empty cardboard boxes from the nearby Western Tire store. They had contained washer and refrigerator floor display models. We made houses and rocket ships of them and traveled to all the nearby planets, in our minds. .Never thought of time travel until “The Time Machine “ movie came out. For that, he hooked up Christmas lights and fault indicator diodes and old radio switches on a piece of plywood, and that was our control panel..I visit my father in assisted living three times a week now. Thanks, Dad.
