For those of going to the Knoxville Nationals, you need to download thier app on your phone. It has everything that you would ever want to know. Qualifying, lineups, results, main event lineups., etc.

While I have bought line up sheets in the past, I would think that having an electronic media would be much better. I know that many of the national series twitter feeds will always have this information. It would be very easy for each track to tweet out all of this information. The POWRi format seems to be the easiest to read and understand.
