It looks like the South Bend Tire Rack tour and auto cross has been pushed back from the 4th of October to the 19th. It also looks like that change may allow the actual auto cross to take place. Good news for those who wanted to do the track event, bad news for those who can't make the 19th.
Please keep in mind that this is not a Chicago MINI Motoring Club event and you'll need to contact Jeff (who is planning the event) for more information.
