SoB was the only ride that has ever given me that questionable feeling, but for that reason alone is why I loved it.

No other rides give me that feeling. I enjoy them far too much to feel anything but happy and good.

Diamondback. I love it, but it scares me.

The Eiffel Tower scares me most in the park.

WindSeeker and even just waiting in line for one of the waterslides is scary too.

Great call on the waiting for water slides. Near the top I will occasionally look straight down over the railing, then remember that I am afraid of heights and will start to shimmy my way towards the exact middle of the steps or platform.

When I was young and still hadn't conquered my fear of heights, the only ride I could do at the water park was Snowy River Rampage (now Zoom Flume)

The ATM

The only ride that still truly makes me nervous is Witches' Wheel at Cedar Point. However, I also get nervous if I'm forced to stand on stairs, such as when waiting for a water slide. I can climb the stairs with no issue, but when you make me stand on them in one place without moving, I start to get nervous that I'm going to fall down the stairs.

Witches Wheel doesn't make me nervous but does make make feel uncomfortable when I get on it. I keep wondering where is the seatbelt, and what would happen if the ride just stop at full tilt.

The only amusement devices I've ridden which still make me nervous are (fast) body slides and mat slides.

Mainly because of the potential of water getting up my sinuses, my head impacting the slide, and/or my skin being abraded by the slide.

The risk of all but the first is low when following all safety instructions, of course, but a potential for injury still makes me nervous.

Not to mention, "What IS in that water?"

Terp, who doesn't take baths with 20,000 people, many of whom desperately needed one, nor does he swim in toilets.

WindSeeker, or any form of cable cars.

Delirium makes me nervous when you swing to the fullest extent, I always think that I'm going to fall off. Besides that, I absolutely love Delirium especially on hot days when you swing back and forth and you get cooled off relatively quick, and you don't even get wet, I can also say that obviously for the WindSeeker too.
