To get from Santiago, Chile to Mendoza, Argentina, you have a few options. I ruled out all of them except for the bus. The ride wasn't too bad, the checkpoint was fine, and the view was fantastic. It also helps that an entire city which exists to serve you wine is the endpoint of your journey. Along the way, you are endlessly dazzled by vistas such as these, which repeatedly show up outside your window for miles and miles and miles.
