This may actually be a more fun event than the actual Grand Prix. Three days in May of watching old racing cars race on the actual Grand Prix track, a couple of weeks before the real event takes place. Races take place between old racing cars dating back to the 40s, racing against each other, and moving up into the late 70s. It is quite something to see how the styles of the cars, how they are driven and how then handle the course evolve over this 40 years period. And how the sound level evolves as well!
They open up the pits so you can wonder around and see the old cars up close while they work on them. The crowds aren’t bad either. A very fun event I plan to take in again next year.
