My name is Amir. I design rides and attractions for theme parks. Ever since I was a kid I was obsessed with toys like K’nex and Roller Coaster Tycoon, which helped spark my creativity. These days I am lucky enough to live my dream, working for Thinkwell in Los Angeles, creating some VERY top secret rides that will make your heads spin. In commemoration of all the amazing roller coaster designers who have come before me, here are the top 10 now defunct rollercoasters that I wish were still in existence.
