Northbound on 67. The clouds are thickening.  There are actually thunderstorms in the forecast.  What is the plan for tonight?  Watching for the mysterious Marfa Lights, only seen on clear nights!  Instead, we are bundling up for a cold windy night with temperatures in the 30s.  Tomorrow night’s forecast isn’t much better but we will hang around one more day just in case things improve on the lights watching front.   Tuesdays are pretty dead in Marfa so we need another day to check out the local attractions anyway.
