It's called Kingda Ka. It's the tallest and fastest roller coaster in the world. At 456 feet tall, and speeds up to 128 miles per hour, it's been a dream of mine (for almost two years) to ride it. I got so obsessed, in fact, I had maybe 9 or 10 dreams (like the dreams you have at night) about riding it.
FINALLY, yesterday, my school took a field trip to Great Adventure (where Kingda Ka is located.) At the end of the day, I rode it. I flipping rode it. The hour wait was totally worth it.
The only word to describe it is, amazing.
