Roadtrip Deepness

Here's postcards of the two cave/caverns we visited, each spectacular in its own way.

 This is a photo of the "bacon" formations, which are semi-translucent. Near Lexington VA (I think).

This cave is traversed by boat and has trout that live in the waters, mostly by the dock in case you toss food. Steep trail and 48 steps down and then back up. Goes out into a made lake with ducks and spottings of elk and deer in their wildlife park all around the cave. And then back through the cave to the dock. It's the only flooded cave to visit in the country.
