Yes one of the memories of going to the 6 days races in DK was the NOICE building up as each race came close to the last lap. Hitting the barriers and stomping on the steps/seats and the motor cycle revving up.
Along with the smoke, yes they used to smoke like no tomorrow in the VIP and coach area, coming up from chimney aka centre bit that was so thick that you couldn't see across to the far side of the track. And then the unlimited amount of hotdogs I could get when I did the beer runs for my dad and friends. Yes back then a 8-10 year old could buy beers for their folks without any question.
