It's just been announced that Porsche is going to build a new North American Headquarters complete with a Track for Porsche owners to play on. It's going to be built on the site of the closed Ford Plant on the South side of Atlanta.
I kind of wonder why they didn't build something up here. VW's HQ is right down the street from my office and Nissan is even closer. If they really wanted to build a track there's land out west of here.
