Shelling is a hobby that can bring back memories of your vacation for years to come. Put on your swimsuit, leave the big cities behind, and go to the east end of Grand Bahama or New Providence at low tide. Wade out to the dark spots in the water where the seaweed grows. There, conch feed in the thousands. There's always someone around willing to clean the shells for you. Sand dollars are common, and literally hundreds of exquisite shells lie on the high water line of Out Island beaches.
