There's an absolutely amazing circuit not far south from me called 'Hampton Downs'. It was the brainchild of two racers who were disappointed when they couldn't get into Pukekohe Raceway when they wanted to.
It's taken 15 years, but they have pretty much self-funded the entire circuit through the sale of land for homes and circuit-side residences for race week(end)s, and commercial property sales. They have had the backing of one of the big banks here who have treated it as a flagship venture.
The whole enterprise is resoundingly welcomed by the NZ government and anyone who has been there. It is a wonderful achievement, and completely compliments the Raceway which is only 20km or so away.
It is <ahem> 'allegedly' F1 ready, but will never be sanctioned as such because some jumped little twerp wants far too much money to sign his name to say it is suitable. The total cost is/was around NZ$60m, and it's nearly that much again to get the last signature required. So it'll not happen.
I doubt anyone is going to be disappointed at this stage. Ecclestone hardly needs the money, and the circuit is busy enough as it is.
Still, goes to show the monopoly one person holds on the F1 circus.
