You've probably heard the legend, take lava rocks away from Hawaii and bad luck will follow. Some visitors might be finding out the hard way.

Officials from the Haleakala National Park say they've gotten more than 1,200 rocks back in the mail this year. They say, they typically get hundreds of returned lava rocks every year along with letters of apology to Pele. The park is warning tourists not to do it. Replacing the rocks is also adds more work for park employees. The returned rocks need to be frozen prior to going back outside to kill any foreign bacteria.
