Another dead end.

Says the 'guide', while laying on the beach in the sun in Barbados, the stillness broken by a sharp 'crack' and loud voices, and my (the 'guide's) curiosity was satisfied by my soon-to-be second wife, who was working in the Caribbean setting up a communicarion network, and whom I was visiting. She told me that what I was hearing was a group of men playing dominoes. I never did 'see' them but 'heard' they were. They sit with a board on their knees and slap down each tile with a mighty crack and an equally mighty roar. Many years later my third wife and I played over 700 games of dominoes but ne'er a slap was heard.
LITTLE FLY upon the beach/ Does your grasp not match your reach?/ You will not feel quite so grand/ When your head is covered in sand!
