Yeah lets keep with the airfield genre going but with a difference
This is RAF Broadwell as was during WWII, it closed and was returned to farmland in 1947. The current RAF Brize Norton is only a couple of miles away.
Use your imagination, go back to 1947 and buy the land, and build me a racing circuit using the perimeter road and runways, and the minimal of new tarmac/concrete.
Now resurrect the old circuit into a modern safe raceway, the money is available to add some new sections.
I've added a line down the centre of the runway 1.76kms is 1.1 miles in old money so that should help with scale. The google earth co-ordinates are bottom right if you want to plan it out on that first.
