When country rocker Gram Parsons died of a drug overdose in 1973, friends snatched his body from Los Angeles and burned it in a place he loved: Joshua Tree National Park, Calif. Later, fans illegally placed a marker in his honor in the park. Now, some say it's time for the National Park Service to officially recognize the counterculture musician as a part of park history. Supporters argue that the park recognizes 19th-century rustlers, miners, and ranchers who left their mark.
