This artist on top of his van was spotted by Ken Ratcliff (a Flick'r photographer) at a public access parking lot adjacent to Fort Moutrie National Historic Park near Charleston, South Carolina. Ken says he was taking part in a bicycling event called Festivelo and the lunch stop was at Fort Moultrie. He unfortunately doesn't have any info about the artist who "seemed to be enjoying himself immensely in spite of a very strong wind. (Source: About.com)
