Miller has their own club for local racers. They hold races about once a month at the track and use a different configuration at each event. Miller has four different track that can be raced on. The East and West tracks are each about 2 1/2 miles then they have the 3 mile perimiter track and the full 4 1/2 mile track that combines all of the above tracks.
This past weekend they raced on the West track. As a photographer, I do not really like the West track as it is not as interesting as the other configurations.
