On a tiny roadtrip with the Maternal Unit, we stopped in Cameron, NC (a small town between Sanford and Southern Pines) to check out the crazy painted barns in the area; they were originally commissioned by David Ellis, a Cameron native and artist who brought street artists from New York and Japan to his hometown to paint old barns as the Barnstormers 2002.
(A note for people arriving here via search: if you visit Cameron, several of the antique stores in the center of town have maps of the barn locations. Not all barns from the original project remain, but quite a few do, and the drive is a nice little loop.)
Full set from the trip is here.
