Sarah works at a popular retail store out here (on Sanibel) and hears the complaint “they’re aren’t any shells out there” . . . often.
Or, the comment “every year there are less and less shells”.
I took this picture just yesterday. PILES of shells – literally! The fact is, you never really know where the shells are going to be on any given day. I’ve tried to calculate the winds and tides . . . moons and positions of different beaches. Complicated equations and over-thinking might yield some outstanding finds here and there, but location changes are your best bet. If you come upon a shell-barren beach (which you NEVER REALLY WILL), try another beach! I visited four beaches yesterday, and two of the four were “goldmines”. The picture below was taken at access one.
