Further evidence that Charlottesville is the center of the universe: 90% of the country’s clay tennis courts are made from igneous basalt mined at Luck Stone. As David Hendrick explains in today’s Daily Progress, their “Har-Tru” surface material is mined in Shadwell before making its way to courts across the nation. In the earliest days of the 30-year-old company, the U.S. Open was even played on Har-Tru for a few years, before the tournament moved away from clay. Today, every court from Farmington’s to Central Park’s are all made by Luck Stone. Small world.
