Here in Victoria, Australia, back in the "old days", a popular passtime was going for lengthy cruises along the shores of Port Phillip Bay.
History has it that enormous amounts of alcohol were consumed on these voyages with the rubbish bins full of empties being dumped over the side once the boat was tied up at its home pier.
Sorrento was one of these piers and some 30 years ago some friends of mine made up a dredge and worked the surrounding area, trying desperately to keep things secret. I caught them in the act and swam over for a look. The amount of bottles they had recovered on this day was amazing and was indicative of what they had been pulling for weeks.
They made thousands out of this venture.
They also dived in rivers with old pubs on the banks or nearby, feeling in the mud for their bottles. Same deal, they found some fabulous and expensive bottles.
Sadly, dredging in all its forms is banned here in Vic, and most if not all states in Oz, denying us of this innocent pleasure and most of the rivers have been worked to death.
But, as no man gets it all, there is still the odd treasure out there waiting to be found.
Lou.
