River Country was Disney's first water park. It was very different from the modern slide focused waterparks. I think the themeing was something like Fourth of July at a mid-American water hole. The focus was more on playing in the pools, sand, and fountains and less on big slides. It was a great place to get away for a relaxing summer day to break up a busy week at the theme parks. I guess part of the problem was that it was relaxing because it never seemed too crowded. That means is probably didn't make as much money as was needed. Maybe they'll reopen it as a seasonal thing now that WDW attendance seems to be very high again.
Alright, TIBM is from River Country, Discovery Island, or a Disney miniature golf course...
