Topix Underground

It's our favorite thing to do when we go to the Smokies.

We would go through there when I was a kid and we'd drive to Florida. I liked driving through the Smokies  better. That was actually the first time I saw mountains.  I was really struck by how the road was cut through the side of a mountain and there was like a rock face on one side. I had never seen exposed rock like that before or red dirt. Michigan is flat.
