Apparently Bernie didn't learn anything when they ran the Grand Prix in Dallas in July of '84. I stood out there all day in 106 degrees just to watch the tops of rollbars go by. Poor Nigel Mansel collapsed in the heat after the race. The heat and humidity in Austin in the summer will make Dubai seem like a chilly spring day. There are so many premier road courses ( Road America, Road Atlanta, Watkins Glen, etc. ) that it seems ridiculous to spend the MILLIONS that will be required to start from scratch. If F1 couldn't draw in Indy, why would they think that the middle of Texas will be any better?
