You can't fly over or near Disneyland or Walt Disney World. The restrictions were slipped into legislation in the early post-9/11 days, but seem designed much more to keep aerial advertisers from cluttering up the skies over the parks (which I can appreciate aesthetically, if not legally) than to protect against terror attacks (only the Disney parks are included, not, for example, Universal, and a three mile exclusion zone really doesn't protect against a terrorist-piloted aircraft from causing mischief).
I don't want to see adverts in the sky over Disneyland when I'm there, but I don't think that should have the force of law behind it, especially under the false pretenses of protecting the public.
No-fly zones over Disney parks face new scrutiny
The “Happiest Place on Earth” has some of the strictest airspace in America.
