Hi,
I was very brief in my post because i had to hotfoot out to pick my son up. What you need is a GOOD track curator with orders from on high to make it a "racing" track with lots of different lines to pass on. Whatever the base surface is, given time, expertise and some expense it can be done. The GPs are THE showcase of the sport. The weather was fine, the track did NOT measure up. This was an "Ole" track with a vengeance and very pedestrian processions, for the most part, resulted. Lets hope tomorrow in Poland brings us good fare. Kindest regards. Alan.
