I can bet this man must have been one of those kids:
"One man drove 12,238 miles and across 30 states in the U.S. to scrawl a message that could only be viewed using Google Earth. His big shoutout: "Read Ayn Rand."(From Gizmodo)
Assuming a mileage of about 30 mpg, he spent more than a thousand dollars (~$3/gallon) to tell the world to read Ayn Rand?
I'm sure the idea of donating a thousand dollars to a library in need would have appeared totally incompatible with his favorite writer's philosophy.
