I would say you will not know for sure till after the Granite City/Pevely swing or the I-80/Knoxville swing. Those weekends will separate the full time and part time efforts as there will be plenty of other races to choose from then.
So excited for the Granite City/Pevely weekend. I hope the drivers are looking forward to it too and travel well. Pevely is awesome to watch winged sprints on so I can't wait to see the USAC guys throwing it in there on the high banks.
