I'd say that code is outdated. That is, it was made before drones were around and really could be argued that it does not apply to drones.
"No person shall operate in any park, any model airplane, boat, car, rocket or other device that is powered by a rocket motor, an internal combustion engine, or other power source, except in an area and at such times as are designated for such use by the director of the department of recreation, parks and community services."
"or other device that is powered by... other power source"
Such as a radio or cell phone?
