Yeah - the Tower of Terror is alright, but I can still beat it to 160k's.
When I was taking it easy up at Willowbank, it got to half track in 7.3 secs @ 168k's. Definitely not 4.5gs though - everyone thought that it looked like a 15 second cruiser when I left the startline. Call me a big girl's blouse, but I had no intention of putting the car into the wall just because I hadn't got around to buying some sticky tyres...
Now, for heart in the mouth stuff - did you try the Giant Drop? The first time I went on that was a major adrenalin rush. It feels like absolute freefall, without any mechanical attachment. I fair dinkum thought that I was about to go plumetting into the ground before that reassuring (and back compressing) decelleration. Great stuff !
