It was announced in January of 05' that Disney's River Country would be permantly closed. Much of the park is actually still there...I know some of my dumb CM friends that still come there at night just to "hang out". During Mickey's BBQ they still use the restrooms and lockers that was used in River Country. Those are probaly the only thing from River Country that are still restored and kept to date. I remember going to the BBQ, and they walled off River Country, with signs on it saying "Sorry, River Country is closed".
It is kind of easy to sneak in River Country because of its shadey-ness and lack of security. But of course, don't do it.
