Todays feelgood story; The kauai garden island news report about woman who found a bottle on the beach. It looked like any old bottle at first, classic beach debris, but when she picked it up she found a dollar and adverts inside.
When she called the number on the ads she found that the owner of the business had found the bottles himself, and after cleaning them up he thought they'd make a good advertising campaign. So he placed the bottles - and the dollar as insurance to make people take the bottle with them and not just throw it back into the sea - in the waters around the beaches.
It worked, as the story hit the local news, alas the name of the advertiser isn't mentioned. Drats. Kauaiworld
