This is an old fashioned windmill - west Texas - used for pumping water - usually for livestock. We did see a few of these still operating as we drove.
We saw this eastbound train as we headed west. (saw several trains during our trip)
West Texas is oil country--- this is a refinery there.
Above is a west Texas skyline in the oil country - no mountains!
Look, ahead - some mountains!! Those are the mountains as we approached the western edge of Texas - getting close to El Paso!!
