Beachcombing for ambergris
Ambergris is a rare valuable commodity, in part due to its rarity and the uncertainy of supply. There are lucky finds resulting in the purchase of a dream home or world trip. Then there are the bitter disappointments; the close but no cigar stories when the earnest beachcomber discovers his unusual find is just a piece of tar or other flotsam. However it pays to keep an eagle eye while walking along the beach. You never know. It could be your lucky day.
