Avignon to Arles. Woke up after our night train (we all slept surprisingly well) to the south of France- the atmosphere changed perceptively: sun baked warm colors in contrast to the deep greens we'd seen up north. Saw the famous Pont d'Avignon (and have had the song stuck in our heads all day!), almost got run over on a tiny street by an even tinier bus, and had an incredible lunch to renew our energy.Headed over to Pont du Gard to see the astonishing Roman aqueduct, loved the museum, and really loved splashing in the river below to cool off!Sleeping in Arles tonight and tomorrow-had dinner just a stone's throw from the ancient Roman Arena. So many great memories, and a very full day.
