We visited our third cavern in less than two years today. First, it was Luray Caverns in the Shenandoah Valley in September 2010, then it was La Grotte de Seythenex in France in June 2011. Today’s underground exploration was at the Inner Space Cavern in Georgetown, Texas. We have visited more caves in the past 18 months than I’d visited during my first 42 years on this planet.
