Sweet! Sounds like we're getting a Disk-o too!
I always had my suspicions about the fountain. Seemed like the only logical place to install a free-fall (bouncing spring?) ride. I only hope it isn't from S&S. Not that I don't like them--I do, especially when they're cranked up. But given the noise can generate over time (VF's farting Turbo Drop, anyone?) it might suffer a fair amount of downtime.
The $30 million upgrade cost is more than a traditional outdoor park would pay. Remember, the heavy demolition / contruction won't start until after 10 pm.
