The floating water slide economic recovery

Wondering what will drive the U.S. economy forward in the coming years? I just got an e-mail from a PR guy for the National Association of RV Parks and Campgrounds that suggests an answer:

If you're looking for a different angle to highlight involving America's private campgrounds, you may want to focus on their increasing investments in unique water attractions, like spraygrounds, floating water slides and water ballon war games. ...

Barbara thinks "ballon" is a typo. I'm saying it's a conscious use of the French spelling, because nobody enjoys water balloon jeux de guerre like the French do. In any case, it's clearly time to go long water park manufacturers. Of which there are apparently 1,926 in mainland China. So maybe this isn't really the future of the U.S. economy.
