I too liked Istanbul Park, can't remember why it was dropped from GPs.
I always thought the first weekend in August was a tradition with WSBK being held at Brands Hatch, until we sadly lost Craig Jones. One reason given for potentially dropping Shiverstone was falling numbers in fans, so now we have two big races at the same track within four weeks, go figure. Although our current crop of racers are doing well, they don't seem to have the crowd potential that Toseland brought. Walking into Brands in 2007 I sensed the crowd were charged and I haven't been to a home race with a crowd that big in recent times. Wasn't there a GP at Donington that only attracted 19,000, that was when Foggy was doing well in WSBK?
