El Loco opened up Tuesday at the Adventuredome, replacing the old “Rim Runner” water ride.
The roller coaster features individual cars with only four seats, plus has tighter turns, steeper drops, and insane twists.
It is the second roller coaster of its kind in the United States and one of five in the world.
The project manager says that building the roller coaster inside the dome was like building a ship in a bottle.
