Pro tip: stop storing tapes upright next to the heater vent, my 1988 mixtapes warped after 2 winters
I kept my whole shoebox collection on a shelf near the vent in my old apartment in Buffalo and the cases felt fine, so I figured it was safe. Then I played a tape my sister made me and the pitch slid all over the place, and a guy at a flea market told me heat does that slowly so you never notice until it is too late. Where do you all keep yours, closet, basement, somewhere cooler?
