Last year, 22 year old Greg Hindy embarked on a solitary year-long walk across the United States from his native New Hampshire to California, in silence. His journey is described in a Boston Globe article, which links to Greg’s website and Facebook pages maintained by his supportive father. The trek is an expression of performance art (Hindy’s chief possession being a large-format camera for documenting what he encounters), but also an experiment in mindfulness and meditation.
