Alabama F1 backup plan if Austin fails?

According to Gordon Kirby " Ecclestone has been guaranteed US$25 million per year for ten years by the state of Texas. But with governor Rick Perry facing a tough re-election campaign and the state contending with a $20 million budget shortfall there are questions about the financial viability of building an F1-style track in Texas. It's said, by the way, that the Barber Motorsports Park circuit outside Birmingham, Alabama is Ecclestone's back-up venue should the Austin dream fail to materialize."
