This is a question that can't have a wrong answer. Why do you love roller coasters?
For me it is airtime. I love the rush you get when you slightly lift off the seat, and get that butterfly feeling in your stomach!
You know, I've really never thought of this question. I guess I'm more in love of the feel of Theme Parks themselves. I love coasters, but I also love the feel of the park, You know, walking at you're favorite park at dusk, just strolling and watching people having the time of there lives.
I love them because of the thrill and feeling on bigger ones that your are about to die. I love the thrill, drops, airtime, and speed. Basically everything about them! :D I love bigger drops because of that strange feeling you get in your stomach too.
