I have another new hobby...collecting sand.  Bill and I traveled to some beautiful beaches on our last cruise.  I couldn't resist bringing home a small amount.  

 The bottles are fun to find as well.

 Most of the sand was fairly typical...coarse, however; the sand in Barbados was so soft.  It resembled flour.  And strangely there were almost zero shells on the beach in Barbados...also zero sea glass.
