From Crackle:
Marc Horowitz signed his name on a US map and then drove that route. Along the way he “improved” 19 towns that fell along his signature’s path. These “improvements” include starting an Anonymous Semi-Nudist Colony in Nampa, Idaho and burying an entire town’s problems in Craig, Colorado. Hilarious.
I think this counts as the “World’s Largest Virtual Signature.” Guinness if you are listening, hear THAT!
(thanks Marc)
