The stern horizon-fenced plains of the Panhandle are foreign to the little wooded hills and sweet streams in the Davis Mountains.

The hot and humid air of the Gulf Coast has no likeness in the cool crystal in the northwest of the Panhandle. And Austin on its hills among the bordered lakes might be across the world from Dallas.
