From CBC News:
Drivers, start your engines — a massive, roller coaster-like go-kart racetrack is now open in Niagara Falls, Ont.
Tourism company HOCO Limited unveiled its new “Niagara Speedway” attraction on the Clifton Hill entertainment strip this week.
“It’s like go-karts on steroids,” said Harry Oakes, HOCO’s president, in a statement. “You drive on a road course for a portion of the race and then spiral up … to about 40 feet, and then come down a long hill … kind of like the way a wooden coaster would be.”
