Colorado National Speedway is possibly the host of the 2011 Asphalt Nationals, not the dirt nationals. It is a 3/8 mile asphalt track and very fast from what I have been told.
I think what they should do to try promoting the nationals more is do something like the asphalt modifieds do it with the North/South Shootout but instead make it the EAST/WEST Legends Battle. Instead of having just one National race for each the dirt and asphalt racing make it a series of sorts. Towards the end of the year Inex should host a National Qualifier event in both the East and West. But locate them so it is a reasonable driving for people throughout the country located east, west, and central. After both East and West events are held for both dirt and asphalt a month or so later have a combined National East/West Battle where the winners of the other events are locked in. When it is all said and done you will have East winners, West winners, and National winners. Now this would give people the opportunity to run a big event without breaking the wallet with travel. It would then be up to you if you would run one, two, or even all three events.
Doing something like this would also be a great marketing deal with USLC with advertising, tv coverage, and even more if they did it the right way. They could also do a bonus where if you win say the East & National or West & National Event you get a $750 bonus, If you want to travel and win all three you get a $1,500 bonus.
I don't know maybe I am way off with this idea but I just think it would be something different or cool to try bringing in more cars.
