With 4 people working together (2 elementary school children, and 2 adult males) we made a much larger castle complex further north on Salt Creek beach, over the course of 3 hours. It was great fun.
When high tide began to approach (towards 5pm, high tide projected to be 640pm last Saturday) the furthest outpost, closest to the shore, began to be battered by the surf's onslaught. The youngest of our all male construction crew wanted to destroy the entire complex before we left, but we convinced him to just let the ocean take it. He reluctantly agreed.
When Dr Desert Flower and I walked the beach on Labor Day (September 2nd, about 40 hours later) there were no remnants of the 10ft x 8ft x nearly 3ft high castle and 1 foot deep moat.
I am getting "the hang of it" now, and have figured out the 'goldilocks' ratio of wet sand to dry sand that is required to make the structure formable and sturdy enough, without having it collapse in an amorphous slurry. It is one helluva work out, and there's something "to show" for it when it is done, so I know this will not be the last sand castle my hands make on the Pacific Ocean's California shoreline.
