Yaas! I love them!! I ride every rollercoaster when I visit theme parks.
The more extreme they are, the steeper, the more loops, the higher it is on the list of world's highest/fastest/scariest/longest rollercoasters, i'm in for the long line, the adrenaline rush, and the RIDE !!!
I used to hate them but now I love them so much, the most recent rollercoaster I went on was Shambhala which is the tallest and fastest hypercoaster in Europe. It was scary as hell but I enjoyed it so much.
