ISC declines to make proposal on managing Laguna Seca: The International Speedway Corporation has declined to make a proposal on managing Mazda Raceway Laguna Seca according to Monterey County Supervisor Dave Potter. The county, which owns Laguna Seca, had been in a 90-day due diligence phase with the Daytona Beach-based ISC, a precursor to any potential management agreement. The Sports Car Racing Association of the Monterey Peninsula has managed the track since it's inception in 1957. But the nonprofit organization has struggled financially in recent years, losing its MotoGP motorcycle race. County officials said SCRAMP had been managing the raceway on a monthly renewal basis since early last year while the county considered the facility's long-term future. Potter says he supports suggestion that a request for proposals be issued for the Laguna Seca raceway management/concession contract.(Monterey Herald)(9-17-2015)
