Aztec….

…New Mexico, quiet and nice little town, which makes us glad,
We needed some quiet, alone time together, which now we have had;
Interesting place here in the New Mexico mountains the view,
Of a civilization long gone from the earth, built to last too.

We did some touring of the Nation Monument park,
But we were glad to turn in soon after dark,
On our way back to her new Tehachapi home,
Home for a couple of day rest, before we continue our roam.

Explanation. The ruin in the photo was built in the 1200's!
