When I was a kid, I LOVED building forts. There was something about planning, gathering, building, and enjoying the fruits of my labor. I always felt so cozy and snug inside and loved pretending it was a boat or castle or a place for my secret club.
Luke and Hayley love forts too. One rainy Saturday, we pulled out the sheets and 10 minutes later we had a fort. They played in there for hours, until one of them (still don't know who) decided to make a "sunroof" and crawl through. It was great fun while it lasted.
