I took the family to Luray Caverns on Friday, in Virginia’s Shenandoah Valley. I haven’t visited enough caves to say how this one compares to others, but it did make this top-ten list and I recommend it highly. It’s also a private business that sells tickets and souvenirs, not a public park that consumes taxpayer dollars. Luray Caverns may not be a model for balancing tourism and conservation at every natural wonder in the country, but it’s probably a better one than most people realize. Americans can perform a lot of wonders on their own.
