A year or two ago, sitting on the beach, watching the children play in the waves, I picked up a couple of small rocks and tried to stack them on top of each other. I didn't think much of it. It was just something to do with my hands while watching the kids and the surf.
However, other people I was with began building their own towers. By the time we were done, we had a number of towers, which were admired by both humans and seagulls.
So I was not surprised last week when I arrived at the beach where my sister and her family were camping, and saw a rock tower. I soon found myself once again building my own tower. That night we camped on the beach, and the next day, several more towers were built. Some towers were built for height. Some were built for creativity. And some were built, hoping that people would look at them and say, "How in the world are those rocks balancing like that?"
