What is a wishing rock? It's a rock with a single perfectly unbroken stripe all the way around the circumference of the rock. For a rock to qualify as a true wishing rock, there can be no splits, no outrunners, no faint second lines on the rock. Most of us have seen striped rocks, but to find one with just a single perfect line is not easy. Popular lore holds that if you keep a wishing rock in your pocket (or nearby) and make wishes on it, it will help your wishes come true.
