Craig Jolly is a young man who has spent the last year and a half walking across the country. He started his trek on Mt. Mitchell, NC, in July 2012. Mt Mitchell is the highest peak east of the Mississippi.
He's currently hiking Mt Whitney, finishing his journey. Bob R snapped his picture, captioned:
