I spoke to Pole Position (not the gentleman's club) in Corona today and we would need 8 or more to get the group rate. For $45 you would get 14 laps of qualifying and 16 laps of racing. For $60 you add 12 practice laps before qualifying and racing. They are open from 10 am to 12midnight and they could reserve a date and time with a 50% deposit. So we just need to pick a date,time and collect the deposit.
