For most shows 1 support class is expected, beyond that the natives get a little restless. This show, on their website, was scheduled as USAC Sprints and UMRA TQ midgets. An all open wheel show! I am sure that some are dissapointed that the 3rd class has been added. It also makes it more difficult to get the feature in early as has been intended by USAC. Lastly one of the reasons that the crowd is getting older and older at open wheel events is that the kids never get to meet the drivers and see the cars close up anymore. Waiting through 1 extra feature before being let into the pits is a possibility, waiting through 2 probably isnt.
