Haven't been on many.
The most thrilling one was California Screamin'.
You know that unbelievably fast acceleration when it starts up? From the outside, I thought it looked kinda slow.
When we finally got through the line, it had been about a half hour, and it was my first ride of the day, so I was anything but prepared. It just told us to 'brace ourselves' and started counting down.
Once it launched forward, a massive jolt of adrenaline shot down my spine. I was legitimately worried of peeing myself.
The first time was fun and all, but the second one was downright painful. I decided that instead of pressing myself against the seat, I should scoot forward and keep my head leaned downward. That was a huge mistake.
I basically slammed into the back of the seat. The neck pains lasted all day, but it was worth it.
