Somewhere in the Caribbean, wind and tide set a worn-out fishing boat firmly in the sands of a sun-drenched beach.   It wasn't long before an opportunistic local had a bright idea and set about collecting scraps of corrugated tin and lumber.  Within a few weeks, he'd cobbled together a fine ice cream stand, set firmly above the water and sand.  Want a break from the baking heat?  Cool off with a cone from "Shiver Me Timbers" ice cream!
