Carl, screwing up a potentially nice picture
at Luray Caverns
Luray Caverns is a great little place to go and only about two hours away from DC. Here is how I recommend scheduling your time. You can drive to Luray, VA in about two hours if you go on I-66 to I-81. Tack on an extra hour if you opt to take the very beautiful Skyline Drive between Front Royal and Route 211, which will take you right into Luray. There is a $15 fee to take the Skyline Drive but it is worth every penny. Just do it.
The caverns themselves are beautiful, filled with stalactites, stalagmites, rocks and other things that are underground. The young woman behind us in line was scared of encountering bats but this is a squeaky-clean cavern, complete with lights, a paved walkway and tour guides who talk about the various things I would know more about, had I paid attention in my geology class. No bugs, from what I could tell, and thus no bats.
