I was about 6 years old and it was the Big Dipper at Great Yarmouth in the UK, used to stand watching it in absolute awe for hours, I was too small to ride that year but the next year I did and it was AMAZING, went on it again last year (aged 40) and it was still brilliant I now can't get enough of theme parks and rollercoasters in general, just wish I had the money to be able to join TPR on their trips
