The REAL expert speaketh! Great post, so informative.
I am actually very impressed by the activities that Jshepherd mentions that Jewelmer does, especially the jazz festival! Anyone who supports jazz has my attention.
I also have appreciated the Filipino Badjao pearl divers, part of an elite guild found around the world.... Maybe Jewelmer could sponsor a pearl diving rodeo/competition and invite the Yaquis from the Sea of Cortez and some Persian Gulf divers- I bet there are still a few -to determine the all time world champions of the osyter grab!
I bet there are Tahitians and other nations who could put on a good showing diving too! Of course they would use some sommon variety of mollusc, not pearl oysters or endangered species
Whereas I think the Badjao may have a more continuous history recently, I think the actual air-holding abilities are probably in the genes and still there!
