Sacramento County's Board of Supervisors formally approved a change at their meeting Tuesday adding drones to the list of "flying model airplanes" banned from county parks.

The county already enforces the ordinance, but adding drones was just meant to clean up the language, according to Head County Ranger Michael Doane.

Three or more violations will cost you a $250 fine for each additional violation.
