I live near this park and I've never seen anyone flying and drones here. As a rule, Orange is a very orderly community, and I'm sure that anyone flying drones in this park will be grounded in a very short time period.
Not in California
I wish I knew the answer to that. I am registered and licenced with the FAA for UAV flight and in my experience, if you find someone objecting to your flight, simply leave and find a different spot.
