So.....since it's a "California Boater Card", does that mean a person without one is not required to be compliant going upstream at Parker, but going downstream on the California side, that person will need one????????? Anyone with half a brain to work with can see another revenue producing law here. Don't misunderstand me, I thoroughly believe that a sizeable percentage of the people I've seen in recent years operating a powerboat should never, ever operate a boat. There's more idiot boaters with money today than I can remember. California leads the Nation in Idiots, however, that includes the California politicians, and every asshole who voted for those Liberal Leaches! PHEW! That felt good!
