We all have roller coasters that we love but they no longer exist. Only memories remain. Personally my favorite demolished roller coaster is Thunder Road at Carowinds. It was such a shame to see it go.
I am 12 years old right now. My first coaster was Hey Arnold's Taxi Chase (now Lucy's Crabbie Cabbie) at Carowinds. I was less than three years old when I went on that coaster.
