Good story!
About all that Glo & myself ever did was to snorkel -- she has some damage from a heart attack, so we couldn't do anything very strenuous while on vacation. When her nephew Marty -- now a missionary in the Philippines -- was a lifeguard at Fort DeRussy on Waikiki beach, we decided to go out into the shipping channel and get some coral. Although it's illegal to do that from other beach front property, That location is a military Site, right next to a major R&R property. So we tucked short pry bars next to our waists and swam the 1/2 mile out to where coral was obtainable. Marty told me that it couldn't successfully be chipped from the decks of sunken barges because it would shatter and be useless.. yep, nothing attached to metal could be saved! So we messed around on the bottom and found a few chunks of coral, slipped them in our mesh bag, and swam back to the beach front. We washed the coral with a high-pressure hose and let it dry out. It sits on our mantle today. In retrospect, it would have been nice to indulge in the entire scuba thing -- I'd only taken a few lessons, but gave it up because of Glow's condition. When the scuba systems first came on the market, a few local fellows set up a dredge, located by the old Argo Mill in Idaho Springs where a small creek runs down from Central City. Gold wasn't selling for much then, but local treasure-club rumor claims they took over $7000 out of that river!
Again, thanks for the story. -- IL' Frank
