"For decades, the NHRA national event scene has pretty much looked the same. Oh, there have been rule changes and some small attempts to change what it looks like, but it’s still pretty much a three- or four-day race, sportsman run on Thursday-Friday-Saturday, pros get two qualifying shots on Friday, two more on Saturday and final eliminations Sunday. It’s the same old, same old… until last year."
