Beach-combing is a time-honored tradition in our family. Shelly and I love to walk slowly up and down the shore looking for agates, shells, bits of coral, colorful rocks or whatever else catches our eyes. Agates are special treasures for us. They are visually interesting and also common enough to be regularly discovered. We have our favorite places to look for them. Sometimes the rocks are all covered with sand and we don’t see them. Other times, the beach looks like a gravel bed offering a rich supply of the opaque beauties.
