the kids and i went for our annual mlk day hike at discovery park. they love to find crabs and good forts on the beach. true found a decent fort, but declared it structurally unsound (yes, he used those words). he thought the frame was decent, but the rest needed a total rework. he pulled it apart, then painstakingly put it back together. i'll admit, his finished work was much neater, and likely more sound.
