To me, there's always just something unsettling about freefall rides.
On one end of this spectrum, the Giant Drop rides are such a rush to me every time even though i know exactly how they work and how they feel. You know, LA is lacking one of these! I miss Drop Zone @ PGA.
On the other side of the spectrum, even though they're smaller, the old first-gen Intamin freefall rides are just terrifying. Never sure what part of you is going to bruse or if it's even going to stop at the bottom of that big L-shapped skid-out run. Scary as hell inventions. Brilliant, though. I still get chills thinking about my first time on "The Edge" back when Marriott still owned Great America.
