One of my first dates with the wife was a trip to Luray Caverns. It's a wonderful, if somewhat touristy and kitschy, place. Its most renowned rock formation was actually created by a clumsy early explorer who broke a stalagmite revealing the famous "Fried Eggs." In honor of that you can get a Big Cave Burger at the refreshment stand - a cheese burger topped with a fried egg!
That's awesome. You've actually been to planet Penmar and survived! ;) Thanks for sharing that.

Thanks Matthew, and sorry I didn't include that originally.
