Graffiti in National Parks

Andre Saraiva, the graffiti artist known as Mr. Andre or Mr. A, has taken his paint into Joshua Tree National Park, where his signature tag has appeared on boulders in the desert.

His infamy peaked in the 90s on the streets of Paris where his tag was well-known. It has a square head with one round eye and one eye that looks like a cross. It has a big toothy grin and long, stick legs.

But his work has sparked the ire of nature lovers in Southern California, where graffiti in parks is on the rise.

Using social media, hikers and nature lovers have started reporting graffiti in parks; and The Modern Hiker community has been acting as an unofficial police investigation force when it comes to tracking down taggers.
