Well, since I'm totally not into doing laundy this morning, I decided to help you out with this one!
I found some fan forums on
www.1branson.com. They have lots of discussions about the parks, as well as other Branson stuff. But that's the closest I could find to any "fansites" on the parks. Also found some discussion there about the Grand Expo, I'll take my findings over to that thread though.
