 Another version often told is that bus drivers, tired of the dirt and grime brought on their buses by the tourists' collection of rocks, started the story at the beginning of each tour to discourage the rock collecting.The myth has caught on, told as if it were an original Hawaiian taboo, and every year countless tourists send these back in order to escape the awful luck that Pele has caused them.So, although the legend itself is probably of twentieth-century origin, the removal of rocks as souvenirs is now frowned upon by Hawaiians.
