I got my hands on a second Cardboard Set. As promised, I'm going to give it away in an RNG raffle. To enter the raffle, just post a sentence using the word cardboard. I'll close this and select a winner after a few people enter.
I'm not like others. I don't get all sentimental about stuff like this at all. If you win it, do what you want with it. You can sell it or auction it. I don't give a crap. Lol.
When I was a kid we had this game where we'd flatten a piece of cardboard, take it to the playground, haul it to the top of the big metal slide, and slide down on it because the metal would have heated up from being in the sun all afternoon, and this saved our butts from being toasted.
