This is a crap idea.
Las Vegas to replace Indy?
F1 boss Bernie Ecclestone revealed he considers moving the United States Grand Prix from Indianapolis to Las Vegas. The contract with the Indianapolis track expires at the end of this year.
Indianapolis might not be interested to renew its contract with the FIA after the tyre farce that happened in the 2005 season. "The deal with Indianapolis expires at the end of this year and I'm not sure if they want to renew our deal," Ecclestone told Autosprint. "At the moment I am looking at alternative solutions to keep the US Grand Prix alive."
"We won't go back to Long Beach," Ecclestone revealed. "The best would be to build a street race in Las Vegas that passes the main road where all the big casino's are."
