Rock skippers of all ages can test their skills during a new event at this year’s Llano Earth Art Fest (LEAF) and World Rock Stacking Championship taking place March 13-16, 2020, at Grenwelge Park in Llano, Texas. The contest is something that Richard Houston, one of the organizers, has wanted to add to the lineup for some time. “It fits the general theme, and everyone likes to skip rocks,” he said.
