Very interesting. I'm gonna go with that "few days" thought and hope that you are right, but continue to wear shoes in the water at the beach. I really just cringe at the thought of putting any garbage in the water, for many reasons, much less broken glass. Saw a pic the other day of a few empty Corona bottles left near the entry at The Baths. Just makes me feel a little sick inside. To me glass and boats go together like glass and swimming pools. Nothing bad happens until something bad happens. Just my opinion. Happy days everyone and thank you for your input.
