I don’t think I’ve ever read anything about tree houses, but you don’t have to tell a 7 year old that a tree house would be cool. They’ll already be climbing the trees anyway, bringing up a convenient plank to sit on, then turning it into a pallet you can sit on together, then to cover it with a roof, and when you find our the rain still blows in sideways with walls, that’s childhood to me.<p>I spent years on that treehouse and then it burned down :(
