I recently did a 27 day rafting trip in the Grand Canyon...One of the coolest things I saw while I was down there (besides the beautiful scenery and the awesome rapids) was a rock covered in heart shaped rocks. Apparently, a couple (who has 60 trips between them) started the tradition years ago. Now, people that have been down before and know what's up bring rocks with them that they've found elsewhere in the canyon to add the collection...
