Looks like it could be a form of "pay to play", except that everyone is going to be "forced" to play. Yet another fee added to the vehicle licensing fee, seemingly the catch-all place to add fees and generate revenue for the state. In return for paying a $15 added licensing fee, all CA residents get free admission to all state parks.
I'm all for it, $15 is a bargain to me for all the parks I visit.
