My oldest daughter is currently walking the Camino de Santiago trail in Spain. She is a writer and in school for her masters currently and decided she needed the inspiration from the 900 km trail.

My wife and I watched "The Way" with Martin Sheen about this particular pilgrimage trail - I would recommend the movie, not a five star movie but it was good to watch and especially to understand some of the things our daughter is experiencing.
So why post that here...thought you would never ask.
I received a text from her this morning, telling me at some hostel they are staying for the night a middle aged German man broke out his guitar and was playing Beatles and Bob Dylan songs. Many sang along, in different languages...cool moment I'm sure
