If I remember right, Quarry bends was the same as it used to be for the 1987 MGP, except that they'd removed the trees and it was altered next year ,1988. Didnt they have to realign it because of subsidence or something. It was much better when you had to point the bike into a black hole surrounded by trees and hope you missed the kerb on the way in and on the way out, much more fun !!!!!!!
