“Wow, a tin cup! Between this and that half tennis ball Bobby found last week, we can go back to building sand castles.” Ed brought a piece of wood that we used as a draw bridge. After all we had to have a moat.
We would pack the wet sand into these strange things that we found, and make a mold for our sand castles. Adults would walk by and smile, and sometimes point at parts of the castle.
We would work hour after hour on our project. Then we would go home. The next day, we would go back to the beach. The tide had come in and gone out and wiped our slate clean. Time to build a new castle!
