>>1100361I used to work at a moving company. We dealt in actual tons of cardboard a day. On slow warehouse days I would tunnel into the cardboard trailer, a 53' truck trailer full of used boxes/ packing material. The way they were deposited would leave a network of narrow passages and chambers, plus you could make your own. Once I had found a comfy cavern, I would play gameboy or shitpost in there for hours.
