As you can see 1978 was the first year for the Corkscrew. The Internet tells me the Corkscrew lasted from 1978 to 1995. The roller coaster now resides in India at an amusement park called MGM Dizzee World where it's reportedly been re-named "Roller Coaster."
Admission in 1978 was $6.50, and adjusted for inflation that's only $23.15 in 2013 dollars. How many amusement parks in North America have an admission of less than $25 today?
