With regard to many of the parks listed, you have a point. Not so with Walt Disney World. You really should look into the vast array of governmental powers ceded to that entity by the State of Florida. While you are at it, take a look at the Reedy Creek Improvement District. Sounds rather benign, no? The fact is that at Walt Disney World, Disney IS the government.
Oh, I know that. Florida pretty much gave Disney anything it ever wanted, and treats them as a power unto themselves.
There's a website around somewhere that details LOADS of behind-the-scenes stuff (and felonies) perpetrated by the disney organization; but I can't find the link to the page anymore. I can remember the front logo was of 'the mouse' in a circular green background, with lowered and sinister eyebrows and needle-sharp little teeth in his grimace.
Does the site found familiar to anyone?
