The United States Air Force proudly presents the 2004 25 Hours of Thunderhill. Come join top drivers from around the country and the US Air Force in this all-out assault on Thunderhill Raceway Park in Willows, CA.

This will be the seventh year NASA has organized this unique race and believes it will be one of the best years ever. Last year's starting grid saw some over 70 cars take the green flag! This prestigious west coast event brings teams from all over the country (and some from around the globe) to compete. Each year the entries are comprised of top teams with drivers such as Richie Hearn, Davy Jones, Memo Gidley, Martin Short, Greg Pickett, Ken Dobson, Roger Foo, and Randy Pobst!

Four drivers minimum are required, but there is no maximum. The entry fee covers the cost of the first four drivers and each additional driver is $150.

Are you ready to push yourself to the edge and find out how good you really are? If so, this is your chance to pit yourself against some of the top talent in the country and see if you have what it takes to sit on the podium of this prestigious event. Space is limited, so enter soon!
