A GPS was used to create a record sized, as in submitted to guinness, maze in a field for corn. "Creating this monstrous maze would ordinarily have required the work of ten men hacking away at corn stalks for a full three weeks, a labor-intensive process Rose wanted to avoid. Instead, he came up with an ingenious solution: He had a special program created for his GPS device, entered his design into it, and, using a map displayed on his GPS screen as a guide, sculpted the maze on a riding mower with just one day's effort."
