Far West Texas, between El Paso and Midland offers some great scenic landscapes and cool things to do. There is, of course, Marfa but head to Marathon and Ft. Davis as well. Big Bend National Park and Balmorhea Springs are close by. And if you are there when it is a little chillier than head to the Chinati Hot Springs outside of Marfa. The Gage Hotel in Marathon is a great place to stay and there are a few cool places in Marfa as well. I say just get out and drive and explore a bunch of nothing (I mean that in a good way!).
I added a link to some more photos.
