This seems to have made a big "splash" on other Disney websites and mentions in the mainstream media, but I'm not seeing any mention here so I will post this.
A few months ago, a blogger posted his trip report out to Disney World's now defunct Discovery Island. For those who don't know, Discovery Island is an island located in Bay Lake, near the Fort Wilderness campground and the former River Country water park. Discovery Island was an accredited zoological facility, and was a precursor of sorts to what is now Animal Kingdom (Animal Kingdom even pays homage to Discovery Island with a section of the park of the same name).
Here's the trip report -- Enjoy!
