Thanks to the homeless guy and his handmade signs, more than one beach visitor expecting cool Pacific water ended up someone rather warmer and slimier. A swim with a dolphin or sea lion or whatnot could be argued to last practically forever if you consider the fat you ended up as, or only about a day if counted your indigestible bits. Either way you shake it, people weren't volunteering for the sort of swim they ended up taking. 83
