The $60 million dollar Duncan track also claimed the neighbours were all onside before construction began. Not so much now, embroiled in court challenges and all. (And it is a roller coaster for elevation change, to reply to those other posts). I think at its peak it was perhaps 15 FTEs of employment.... now less than 10 FTEs
Looks like a bore to drive and for spectators, if there will be any. No elevation change is absolutely unforgivable. Another thing that should be unforgivable, but will not be for "Look at me I am a racer!" types is the absence of a Lime Rock Uphill turn or a very high speed sweeper, such as the old turn 5 at Watkins Glen. If you cannot kill yourself or come close, if you really screw up your driving, there is not much challenge ( I used to race, so don't come back to me with the "safety is everything" line) and the racing spectating is degraded, as spectators will likely be kept too far from the track because of excessive runoff area.
