I have nothing on the other whitewater parks. If I remember the history right...it seems after they went into partnership with someone and built parks in Grand Prairie, TX, Oklahoma City, Georgia, and a couple of other places, they started having some sort of difficulties with the partner, I cannot remember if it was a clash of personalities, financial issues, or a combination. All I remember is that it was announced in a company newsletter that SDC, Inc. (as the company was known at the time) had sold off all interest in the whitewaters, except for the park in Branson that they kept. I think the Whitewater chain was an early "lesson learned" for the company, and they moved in another direction. Now they are the largest family owned theme park company in the nation. Hmmmmm...they MUST BE DOING SOMETHING RIGHT! (Happy 50th Anniversary!)
