Well i thought i had better delve into the forum with guns blazing and educate myself !!
My father lived half smile form Crystal Palace an din the mid 90's when i was working for him i was living there so one night i took my bike and rode up to the Palace and around the track as i recalled seeing this race on TV many years ago as part of BBC 100 great sporting moments programme.
I was surprised at how much of the track existed but it is now narrower than in its heyday- I was too young to know abut motorpsort when it was still an active circuit.

Monza is very similar in concept as it is set in a large park next to the houses so IF any of you guys travel to euroland and want to take in a GP make Monza in September the place- the atmosphere is electric
next choices Silverstone for the motherland GP and Spa

That race was wild !
Gerry Marshall died few years ago but he was a great entertainer at the races with Baby Bertha
He liked a drink or 3 and it was folk lore he was often pulled from the bar by the oily rag to go and race!!
