Is there fuel for sale at the track?

There is self-serve gas available for sale at the track.  It accepts Visa and MasterCard.  Alternatively you can buy gas during the lunch break at the gas stations in Duncan, but this is definitely Not recommended:  it’s a lot of rushing around (when you should be resting up and fueling your body!) just to save just a few dollars off the track pump price.   Remember that bikes have small fuel tanks!
