Powri ususally list a flyer with all the details, When, I have no idea. Last years was cancelled on a forcast of 14 inches of snow. But 2012 had 68 midgets. I think I got there at 3-4 got the pit pass and they raced from about 6-1030, They rework the track often but depending on what they do only takes from 5-15 minutes. just enough time to catch a Restroom break now and then.
