Being a road racer, I cannot fathom being able to wrap my head around a 38 mile course. Tracks I've raced at:
Road America
BlackHawk Farms
Putnam park
Grattan
Gingerman
Brainerd
MidAmerica
Gateway
VIR
Carolina Motorsports Park
Jennings
Talledega
Roebling Road
Daytona
Barber
USA International Raceway
& oddly, I can see doing essentially a lap of all of those linked together, but not with stone walls, curbs, buildings, poles, fences, gates, & dirt mounds everywhere. The speeds attained there are insane. 200mph on the 1000's.
me & 2 friends are going next year. I'm trying to get Cal Crutchlow to let us stay at his place! Lol
No......really.......I am!
