@PaydayPsyduck asks
quick question, is keeping card boxes on the basement floor a bad idea even if the boxes have lids?
Jeff answers
I'd raise them off the floor and choose a dry, stable location. A lid doesn't make an ordinary card box waterproof. Remember @KitchenTableTrainer's sandwich bag? Better storage means thinking about the surroundings as well as the container. Think about where water could reach before it does.
