I was working on my rainwater setup, when I had to remove the cardboard box that was around the 275 gallon plastic container.
Instead of recycling it, why not build a fort for the Little Girl.
Of course, it quickly spiraled out of hand. I built a two-story cardboard clubhouse, INCLUDING a cardboard ladder AND a cardboard slide.
There is a really simple 2x4 lumber frame under the slide, and the roof is clear plastic, but EVERYTHING else is cardboard.
