Interesting. Definitely hinting at a water attraction I think, which the park sorely needs more of. Just think how many weekends during peak season the park sees 100 degree weather. I don't know if I really see them adding thrill slides to this park though since they have White Water...
The log ride just doesn't have enough capacity to keep up, and WWW is for kids. So the river rapids is the last ride I would expect to see them mess with. It's also honestly one of the best that is still around seeing as it has some really nice theming. Then again it's also probably expensive, takes up a lot of real estate, and I could see it having worse ridership than it should due to how hidden it is within the park.
Years ago I said that what I would suggest is taking out the go-karts and putting in a splash battle. That would be a great compliment to the rapids and provide a much needed family water ride with high capacity and engagement for kids. That was back when the go-karts barely functioned though, and now I'm sure they are pretty profitable.
I think what I want most right now is for them to totally overhaul Wildcat though. Just a complete GCII rebuild where they tear down the return run and start over. Or even just retire the whole thing and build new.
Maybe they can just squeeze something into the wildcat infield.
